Holly cow those look like they are in another ZIP code, LOL. Water test Sunday :ernaehrung004:

Agreed.

I think part of it is how low the bracket/platform is mounted.

Really exaggerates the separation.

Umm what happened to the skegs?

One was welded when I bought it.. Then it got accidentally knocked off pulling out of the shop. All welded back on now.

Have to go get the G3 laptop to recalibrate. When I did it the first time, I didnt have the 2nd clean power for the P motor. So, I calibrated individually. Apparently it didn’t like that, so now Im having issues with the keys. I think I just need to calibrate both at same time.
Steering done, and then if rain holds off.. sea trial!!!

What do you mean by clean power?

Gotchya. Was hoping you didn’t whack something first time out because they’re set so far back or something like that.

The newer outboards have a “clean power harness” that feed battery power directly to the pcm. They used to run thru the rigging hose and now they are run to a rigging center. But I bought all new harnesses which came out in 23’, so my 21’ motors required a lil adapting!

Well.. after finding a faulty kill switch module. I finally got her in the water!!!

Used the props that came with motors. 23.5p rev 4 XP’s. Apparently these are different than the regular Rev 4s that I was running before. Longer barrel that provide more stern lift and less cup for less bow lift. Boat ran really flat and trim wouldnt bring the bow up. RPMs were around 61-6200, so im close but may need to try some 23p Rev 4s. I have a set of 25p Rev 4s that worked great with the sterndrives, so I may try those just to see if I change the attitude.

Water pressure was good and made a top speed run of…….drum roll please…dum dum dum

77 MPH!! Thats with full fuel (~180 gallons) and 2 guys in boat! Previously only ran best of 68mph light on fuel and just me.

Tried to lift the jack plate, but I was getting a water in fuel alarm. Figured out later, I dont have onboard filters and no sensors.. so bad wire or something. Ordered new fuel filter/water separators with sensors today. Hopefully plugging them in will fix the alarm.

Then I need to take it back out and run it at the 1/2” higher and then keep going to see how slip and handling react!!!

Thinking I can get closer to 80, especially if 1/2 fuel or less and getting Rev 4 props to get bow up.
I have a few sets.
23.5p Rev4 XP too much stern lift and made for stepped hulls
25p Rev 4 Ran great before but will a lil tall for the outboards.
25p Mirages labbed by Bblades. Not a fan of 3 blades, although ran 69 1x!
Probably need 23P Rev 4’s.. Sooo.. I’ll try the 25p Rev 4s to see if I can get the bow up and go from there. If that works.. I’ll just need to swap or get some 23p.

Boat was really stable but rode really flat, but felt pretty good!!

Some more shots of the Transom

https://cimg4.ibsrv.net/gimg/www.off...629f76195.jpeg

looks good in the water

maybe i missed it, but why not simply bolt the jack plates directly to transom, instead of adding the extension then bolt jack plates on it?

so you can have more trim effect / less drag / faster speed?

Set back puts drives in cleaner water and more leverage.
I only put the jack plates on b/c no one had done this before to a 33ol, so I needed to be able to test different drive heights vs rpm, slip and performance, etc.
either that or I would have had to remove motors and move manually.. so I added manual jackplates to set it up for overall performance and leave it be!

Not really looking for all out speed, but wanted overall performance with ease of adjustability while testing this never done before setup to a baja.
I also knew that in 02, they raised the x dimension and gained 4-5mph with same HP, so i knew raising the drives woudl help, but again, didnt know the secret recipe.

In addition, these motors are 700lbs each and a lot of torque.. and the bracket gives a lot more support and I still wanted a platform off the back of the boat.

Wow!

Very impressive.

Id say, for first time out, you hit it out of the park!

Well done sir!

Anxious to hear how testing goes.

Id send you some wheels to try but none of my junk would work on those motors 🤓

Great work here and efficient as well.

I start getting excited when motors start going on/in, but then its usually another year before we see any water tests. Amazing how quickly you were able to get all this sorted.

How often do you run with a full tank?

on my side i would say quite often !
start the week end full, end often between 1/4 or 1/3
don't feel like going much lower than that to suck whatever can be at the bottom of tank
don't feel like starting 1/2 either and waste time fueling twice per week end... so...

I do exact same.

Usually we are running Around the house. Long run in a weekend would be 40 miles round trip, so we normally start weekend just over a 1/2 tank and that will last use the weekend. If we plan on running out of town, maybe 1x a month at best.. we may fill up.. other than that, we are just running around the lake and floating/drinking

I didn’t fill mine up very often, but when I did I remember it was a pig.

If you’re running it at 1/2 tank, you may be ok prop wise

I almost always start with a full tank, since I have two boats when I take the fountain now its almost always a 80-150 mile run.

Absolutely awesome! You really gotta be happy with how good your first sea trail went. I know mine went really good also but I sorta took it for granted. Boat looks awesome and happy to see you get her in the water!

boat came out very nice with the o/b conversion
believe the platform and standard gearcases down deeper in the water is a good set up for the baha
baha is a full pleasure boat and bit heavier than some other brands of hulls
if tried to run sportys with motors on the surface would probably have a harder time getting on a plane
and more slippage at lower cruising speeds wanting to come off plane
did nice job on the conversion and good results 1rst time out

Yep. I may try my 25p Rev 4s bc they should have more bow lift than the rev 4 XPs.
It’s running really flat and I dont get any bow rise trimming up.

If they work, I can bend them down to get my rpms at 6300ish. If not, I may just cut some barrel off the 23.5 Rev 4 XP and add some cup..

According to my resaarch the XP props are good for stepped hulls and lifts the stern and have less cup.

That thing looks killer man. Hopefully I'll catch a glimpse some point this summer. If you ever see a Sonic Prowler around the Eden isles area, it's me

Are you on Pebble Beach? I thought I saw a Sonic headed back to a friend in the Inlets.

The 33OL is only 7500 dry with the inboards. Probably under 7000 now with the O/bs.

Cav plate was 2-3” out the water and still need to finish sea trialing to jack up and see what slip and overall handling does.

Great job boat looks killer I had a 2000 33OL back in the day and luv'd it

There’s always inside rotation to get it to gain more bow lift…. it’s not as easy to do as it is on a bravo tho

Yep, that's me

I tried the 25p Rev 4 and seemed to move the bow around. I kept getting an exhaust overheat shutdown. Come to find out the water hose going to the exhaust came off.

I’ll try the Rev 4 XP again and adjust as needed. I’ll probaly adjust the 25p as well.

I am definitely not turning IN. I tried that before and it was sloppy and reverse sucked. Now im 6” closer together.

I also definitely need some seat time once I get the bugs out the motors.

Trim is a lil weird…. I marked where neutral was and it seems to not take much trim before porpoising at low speeds (below 45) but I normally run 50+.

Wiring harness was giving me problems on Port. Now it’s not getting full boost, ordered new bypass valve and a coil to see where the problem is. Damn gremlins. Runs great to around 4800 and jumps up on plane like a Biatch!!! Its ridiculous!

Sweet pics! Not fair on the gremlins!

Oh. this is s good one!! After a couple weeks of trying to figure out why I couldnt get over 5k rpms.. I bought another fuel gauge, tied the boat to the dock (lifted the lift so the motor would cavitate) so I could test wot fuel pressure. It spiked to 60psi!! so that was working!

Then I decided to change plugs, even thought I had just done that prior to the NO Start issue.

WELL!!!!!!!!!!!!

Most plugs were barely tight, but at least 2 of them were not seated on the head. No pressure at all to remove!!

So... gremlins resolved. Loose spark plugs!! OMG!!

Was a lil rough to be in the lake testing wot, but I did hit 78 during 1 pass, but I may have been going down wind in 2ft chop. Will finish setting up to find best all around height, but runs Great!
1/2 fuel and just me in boat.

Handles better than the I/O.

also. I need to run this MPG again now that i have full compression, but this is what I had with loose plugs on stb motor
43mph @ 1.69mpg
47mph @ 1.59 mpg
50mph @ 1.53 mpg
55mph @ 1.35mpg.

Ill rerun these speeds once I get the find the perfect height w/ best slip numbers.
Above it was betwen 14 and 16, but I/Os, I could get down to 12.
I also need to figure out the best trim height as it doesnt need a lot of trim with the added leverage of being 3ft back!

Please take some video next time you are out to share with us. I want to see this thing ripping!

Im sure i'll get some video.. Sunday was the first day I really had her running again after chasing the fricken loose plugs for a while.

She definitely runs a lot better AND I can get up on ONE motor if needed. Motor jacked up, a lil tab and took her up nice and easy!!

Overall, it rides a lot better. Im still testing heights with the 23p Rev 4's (bent down from 25p) and I also have some 23.5 Rev4 Xp's to try again, but they dont have the tip cup that the regular Rev4 have and according to merc site, they are for big "stepped".hulls. (so think stern lift)

First couple test runs with the XPs, it was hard to get the bow up and ran really flat... BUT, that could have been me not trimming enough.. its a different animal now!

and she literally JUMPS up on plane with only 3k rpms, but I can push her harder, since I was used to being nice to the B1 lower units!

Cruises nicely at 50, 55 60, and 70 mph!! Obviously, I will not be cruising for long period above 60, but it can!!

Took her out monday with the wife and 1/2 fuel.. She hated the flat (looked like glass) water, not having steps. WOT was only 6100 at 72-73..

78 was 2ft chop and windy!! and probably either cross wind or downwind, I was more worried about holding on b/c I was trying out trim and she started chine walking... LOL.. Yep... definitely had too much trim!!

Boats running Great! Jumps on plane. Cruises nicely between 50 and 70 LOL. At 50, im getting 1.5 or better mpg. Was around 1.3-4 with BBCs.

Swapped back to the 23.5 XP rev 4s. Boat definitely like those better! 4 mph difference. Flat water, 100 degrees, 3/4 fuel and me. 77.8 mph at 6300.
I figure with a light load and chop, she would be close to 80!

Also gelcoated my transom black. Still need to add another coat and sand/buff, but looks great. Added a bimini extension as well.
Platform is at a great height to climb in and hold my ice chest where I can actually look inside!

80 is cruising!

Great results all around.

Well done sir.
You should be proud!

Can’t believe there’s still so many old school fans who refuse to consider outboards. To each his own.

Your boat looks great and the numbers are excellent. Enjoy. :)

RR

Finally got a video! We were running around 55mph, then saw I was being videoed so I took off! This was running around 75mph! Had to shorten video and crop so it would upload!

Looks like it runs perfectly! Like it's meant to be!
