A little trick that I have had to do to keep the cables from leaking was I took some of the good 3M shrink wrap and put a couple of layers over the cable we use the type with the glue inside and do one at a time heat it cool it a repeat. Regards Dan and always use new bushings Merc Part number 23-845970 . Good luck.

kplane issue since day 1 i think is resolved, first a new pump then some wiring that had to be put into that blue loom, threaded thru the cushion clamps and those screws resealed
it had to look like i wasnt in there.
next the cable thru hulls arent big enough for cables to go thru so 2 drill motors and 4 bits later and cables fit thru them.
the holes behind the kplanes that the cables originally went thru had to be cleaned out, and dowels glassed in.
the brass plugs are solid, so cushion clamps got thru bolted to hold the cables, now all indicators work.
vinyl sauce is some good stuff, the lightning bolt material is from 95-96
last time at a spoil island caused me to remove all the raw water hoses and backflush the coolers and the heat exchanger needed new orings and gaskets,
my fault on that one, but it was a good day.
unintentionaly ran it down to 4 gallons of gas and didnt run out.
prop is next, the 25 m plus hits 5150 w/ 3 adults, full fuel, cooler, gear, etc.
truck and trailer need rubber before it hits the highway.
other non boat stuff keeps it out of the water for another week.
boat is everything i expected and couldnt be happier.

It's great to see you have you have your boat in the water!

hblair 07-31-2019 04:02 PM

Great looking boat Dan. I'm assuming you're enjoying the summer boating down there in Florida? Feels good seeing the boat in the water huh?

Anyone know how to get in touch in outonsafari? I have tried PMs with no luck, I am interested in some parts he has for sale, please message me with any info.

outonsafari 11-20-2019 10:36 PM

a little update, so this is not a good place for the camera, pic 2 is around 3500 rpm and pic 3 is wot.
the video is all noise and spray.
picked up a garmin gpsmap 78sc and a ram mount, it works perfectly and i can see the screen no problem at wot and regardless of sun. used it today first time.
box stock 25 rev 4 is consistently running 72 @ 5130 rpm think i want to try a 27 mirage non plus if i can find one that isnt molested.
for fun "fed ex santa" will be delivering tomorrow by end of day a 1960 6 foot 94 branch aluminum evergleam complete with color wheel and rotating stand that plays jingle bells. cant waithttps://cimg1.ibsrv.net/gimg/www.off...203b4f4432.jpg

outonsafari 01-19-2020 02:48 PM

today i layed out the hook, its fairly consistent chine to chine but im only concerned from the keel to the outer strakes.

looks to be an 1/8" with the leading edge of it about 6 inches in from the transom.


the bottom was never wet sanded clean and buffed, i just swiped 610 on 7 or 8 spots and said ill get to it.

well im gettin to it now. This is more of a clean up than a truing/sanding but it is gonna get scuffed with that in mind.

By some miracle it gets me a 1/2, then itll come off the trailer and get sanded for another 1/2

Dans about to build up some popeye forearms. Looking good.

outonsafari 01-23-2020 04:53 PM

Heath i hope its not gonna be that intense !


Spent some time double checking X then marking the indicator for level on the tabs too.

prop shaft is 4 3/8 which matches my notes and corresponds w/ the hook being an 1/8

and "the best guess "propshaft height being 4 1/2.


i think there's a 76 hiding somewhere in there and im gonna go after it.

have some tests and some stupid tests planned for next week.

I would tap the top 3 water inlet holes and put SS set screws in. (for testing )Then test and keep a eye on the water pressure ! That is if the lower unit doesn't have low water pick up ? Can't see it.
Just a idea.

outonsafari 01-25-2020 04:55 PM

Tested today but conditions favored the boat. Windy and choppy, not calm and nice like the previous tests.


Speed it ran today has nothing to do with me sanding the bottom it was all in the chop,
(more like scuffed it clean in the general direction of water flow)



Made 2 passes from christianson landing to sebastion inlet and back, very short day.

I let it run for a maybe a minute due to traffic so it never got a chance to settle in,

First pic is slowing down from wot and you can see how much trim it wanted

wot pics/footage is just misted out cant see sh!t

last pic is level trim at a lower speed that i'll get into after theres more time to go thru the video

1 inch spacer 25 mirage plus no ring, air temp in engine room @ wot was 95, full tank.
conditions sucked, port tab crabs the heck out of it and some chine walk because of it.
hit 71.9 turned 5120. Cant say they happened at same time but no matter how the math is done
speed is down 1 slip is up 1.

before spacer the 25 m plus would go into soft limiter @5150, i have 5180-5190 on other videos.
and speed was 73.4.


outonsafari 07-29-2020 04:29 PM

Nothing here really but air temp, camera does not show conditions wind over starboad usually needs no extra port tab but it did today.
I'm convinced tabs need to be horizontal to stop it from crabbing which makes chine walk,
but will finish this year off with spacer, i mean theres an hour on it, so it might get me something.
moving the tabs if it comes to that is gonna be a pain

like to hear any input (already know it needs a better driver)


outonsafari 07-30-2020 03:09 PM

First video is South other 3 dash cam is north. First transom cam is south, second is north from sebastion inlet.
boat down on speed up on slip add chinewalk, bad chinewalk see dash cam, it did it bad thruout all vids.

Spacer has to come out 3 hrs on it 25 minutes at wot maybe.

Chinewalk 50 seconds vid2
Chinewalk around 2 minutes vid3
Kayaker crossed channel, blew a good run vid4

Great documentation Dan! Thanks for sharing, very interesting stuff.

IGetWet 07-31-2020 09:38 AM

Did you run the mirage plus with the full barrel? Is it full labbed or just barrel removed?

outonsafari 07-31-2020 07:41 PM

The 25 m plus is from the pair that was on my 30 scarab, they where modified from the rake angle up to the cup along the diameter, i sent it to a prop shop to return it to stock, they said they did. To me its still in there and i reconditioned props for 4 years,

used to use the old gauges too, wish i had a diameter table and gauge now.

it chinewalked very bad so i cut the ring down 3 times 1/8" at a time and it improved greatly.

it likes to run parrallel to maybe 2-3 degrees trimmed up.

the chinewalk is 95% percent non existent, total confidence to let it run but it goes into the soft limiter.


the 27 m plus really looks box stock ( no where near as progressive on the rake angle) and it has the whole ring on it.

it likes alot of trim 5-6 on the indicator (2 is parrallel)

the chine walk is 95 % non existent, total confidence to let it run but it only turns 4900


other difference between the 2 props is the 25 has vent holes that are plugged, the 27 does not have them at all.


without the spacer the 25 and 27 jump up on plain and i take it easy getting up.

both props cavitate around the 1500 mark for 1/2 second, then once the bow falls and until the boat settles into 2700-2800 rpm any input to the wheel or trim and they will cavitate.

the cavitation is a 50/50 thing it will either bark at you or it will howl and vibrate and you have to start over.


with the spacer cavitation is gone at the 1500 mark, and virtually nil with input once up on plane.

the 25 now stays inside the limiter and wants alot of trim 5-6 on the indicator, but speed is down slip is up and bad chinewalk is back in my life so i didn't see a reason to try the 27.

without the spacer the 25 gets 73 @ 10% slip, the 27 gets 74 @ 11% slip.

plan to remove spacer, cut ring on 27 and cross fingers.

i'll get a couple pics with the straight edge to show the rake early tomorrow before the hurricane panels go up.

i dunno, the more i look at and feel the blades i dont think the 25 has any more, it probly is stock or damn close.
the finish could easily be throwing the look and touch off.

dont ask how i measured how much metal came off, alot of metal came.

outonsafari 05-14-2021 04:13 PM

Took the radio out to use in the ski boat, swapped in a gps speedo (for75 bucks i'm sure it's accurate)
I'll go with whichever one tells me the fastest.
Snuck the antenna and on/off button thru fuse sockets, all fuses under dash.
Even with careful drilling, filing and fitting i still managex to screw both sockets up a little.

outonsafari 06-15-2022 04:19 PM

I'm listing hart throb for sale. It needs a trim ram for the starboard k plane.


i have a complete driveline, bellhousing to hangar with new bearings installed by a mercury dealer at mercury rates. all installation hardware in mercury bags, unopened. I didn't have ujoints installed because the shaft would have to be sized for what i wanted first.


For those who don't know or don't remember during the rebuild, the engine is moved 1 foot forward using an imco stand off box driveshaft, hence the multiple mounting/set up options, also this boat was laid up in the mold as a raceboat with race bulkheads and no cabin, raced 1 season back in 95 or 96.

the engine can go forward another foot and use the bravo driveline. Or a big giant blower can go on, (the engine room is that big)

the drive can go on a box and the driveline can be used.

the drive can go on a box and the engine can be moved back

the plumbing, wiring and steering hoses are rigged to accomodate any repositioning of the engine a foot in either direction, and there is a second battery platform all glassed in.


all the plumbing steering and wiring harness was new when restored and i put about 100 hours on it since the rebuild.


there are 2 complete mounting options:

1. mercury single engine front offshore plate brand new unopened, and 1 mercury single engine rear offshore plate installed on boat

(boat has a 496 so it uses the gil 496 offshore mount up front. The pcm is stock, the engine is stock except for the plus 6 inch inch cmi header kit with oil filter mount and some plumbing changes with an hoses to clean it up in appearance).

2. A complete mercury driveline mount front and rear new unopened with mercury hardware unopened, the rear mounts bolt to either a bravo driveline or a borg warner trans and set on pedestals however, there are 2 brand new unopened gil 496 mounts that can be used with the mercury driveline mounts which tie the mounts together like plates from stringer to stringer.


everything else including mercury stuff for the drive, leftover parts not used in the rebuild and all fluids go with it.


there are 2 driveline/transmission bellhousings, 1 is top mount starter depth with rear offshore plate, the other is top mount starter depth without rear offshore plate.

one is installed on the boat, the other is boxed up with the driveline.

the driveline is in a compartmentalized crate packed in foam so the paint doesn't get scratched stored away at my house.


the tires, bearings brakes and springs on the trailer have 50 - 60 miles, the trailer is set up so i can single hand it on and off and the boat lands within a half of an inch front/back everytime easy peasy.


35 takes it all, boat, parts and trailer. 30 takes the boat and trailer. push button and go. I'll seatrial and talk to anyone who's serious.

outonsafari 06-15-2022 04:31 PM

Couple months ago i put a new horn on it too

anyone recognize it

jeff32 06-15-2022 05:01 PM

Why are you selling your project? Sad ending...

hblair 06-15-2022 05:16 PM

The horn is hilarious. Did you just get tired of the boat? I've been tired of mine for 4 years lol

outonsafari 06-16-2022 11:54 AM

Love the boat, it runs and drives great, just tired of boating in general, too many type A, 4 a-hole people at the ramp/on the water followed by more pre and post hosing washing and wiping than actually boating. There's also a full length cover that goes down to the chine, faded but made from really thick stuff, towable hurricane/100 mph cover made by p&g canvas
30 for everything 25 she's yours.

Curious...I've followed your rebuild threads and you've done incredible work!
Do you work in the marine or auto industry?
How do you find the time.....are you retired?

JaniH 07-04-2022 04:00 PM

Good read 👍 what i think is amazing is how well the mirage plus grips at 4.5" prop shaft height. My prop shaft height ended up to 4.7", and i have bought 5 and 4 blade props for the first tests 🤣.
