The 2.5s' are a piece of cake to rebuild. Much simpler than a 4 stroke with a valvetrain. I don't have any experience with the 300s' so I don't have an opinion on them.

lol three motors will do it easily :party-smiley-004: I say go for it :D

oh and mine goes only as fast as the truck will pull it right now...lower sitting on the back seat floor board of my dodge right now :eekdrop:

If you guys would come down here and run in the ocean with us on a normal day top speed wont matter. 80mph will be fast enough!
Not this lake and river stuff LOL

So does that means you still had intrusion issues even with the new seal and vent kit??

Tell you what we will come south if you come north to LOTO on Shootout Weekend. We can compare water then!

I would love to come down sometime double! real ocean running right?
no water intrusion that I could tell. There was a hint of H2O but it was very, very little so it was prolly just what I didn't clean out before the seal upgrade. Bearings in the port side sound awful rough and I don't like the amount of slack in the prop shaft either. Pulled them both and just dropped them off at Simons in Gonzales to go through. Hopefully no gear problems. The boat was run in salt water and when I drained the lowers before I took it out it had some water in the port lower so I'm thinking the bearings got pitted due to sitting up with salt water in the lower.

I went to loto the first year I had the sunny for the shootout....great time and the water does get nasty, wife hated that part LOL.

Hopefully next year when the motors are done. Would love to make a run on the 1 mile course and have some fun with you guys... I bring my ballast! LOL

No ballast allowed. This is definitely a testosterone weekend!

Sorry for the thread hijack. Now back to regularly scheduled posting.

I did reserve two rooms at Camden tonight so you guys needed to fix'm up hitch'm up and drag them to LOTO.

what would be really nice is if all us outboard guys could make it to loto one year! I may be able to do it next year but this year there's just way too much cr@p on the calendar already (don't tell my wife I called it cr@p :crazy:)

Noli, Shaun installed a modified exhaust tuner, light weight flywheel, water crossover system so I don't lose water pressure in turns, installed a water dump on the side of the bottom pan of cowling(helps keep water spray off the motor) When I first went to Shaun, my cruising speed @5000 was 80mph and my WOT was 105mph.......after Shaun cruising @5000. 90mph. ....and WOT is 116mph. ......"Maritime eng" OSO member was on board for the run........Shaun said out of the all the 28Skater he has worked on or driving. ..my hull is the fastest...
My experience with Shaun was Class Act.......

Steve are you turning your motors in or out? What RPM are you turning at 116mph?

Steve is 100% correct that I was onboard during the setup runs. It was very impressive to see the differences in the before and after runs with this boat. Shaun is a friend of mine and has also helped me on my boat and the results have been very good. I have and will continue to stay out of this discussion because it is none of my business.......

interested to know too. Harry claimed he did 117mph with the in 28 I have.

Turning in. ...Dewald props....rpm @ 116 is 6400-6450, Readout is from my Sc5000screen.....

I'm registered for this year. The wife and I are really looking forward to it

hows the engine work coming along?

As soon as I get the one power head back from diamond, I'll be set with the engine work. Just drop on.
I'm going ahead with shipping the 3 original sportmasters to Craig colabella performance for rebuilds

David
Sorry for all of us to hijack your thread with all this other stuff and get sidetracked!!!!
Hope you get your boat back together soon. Let's move this BS stuff to Craig's new thread where it belongs!
Carry on.

No worries, it's all good!

you have signs of wear or just staying ahead of issues?

I had one lower with some water in t he lube, the other 2 Just preventive maintenance, put them all on 1 pallet for shipping

David,

Any engine progress to b shared yet?






.

Target date for Diamond shipping powerhead and also receiving back the 3 sportmasters from Colabellas is approaching so I've been doing some things to get ready.
one thing I've been wanting to do is switch the center drives to rotating outwards. It seemed like the the stern wanted to buck upwards the last time that I had it out in calm water. The skater handled great when the water had chop and boat wakes. Also the steering wanted to yaw upon backing off the throttles when going over 110. Peter had mentioned to me that due to having the outside engines spread farther apart to accommodate the quad setup, the distance for the outside ones would not be the ideal 3" from tunnel wall. I may have to lower outsides some to get better bite.
There has been a lot of talk about which way to spin drives on a skater. The consensus is that in most cases, spinning props in, increases speed on stern heavy inboards and smaller outboard skaters, but with slight decrease in handling.
However with my 36, it is bow heavy and I'm wondering how spinning all props outward would affect lifting the bow instead, to pack more air and reduce wetted surface.
Currently the set up is outside props outward, and inside props inward.
Since there is very little data on quad outboard setups and none as far as a 36 skater quad outboard is concerned I am in uncharted waters.
I can say this again, that in rougher conditions the bow stayed up and handled great even when backing off throttle. But in calm conditions, it was a totally different animal. This concerns me most right now since I am setting up to run at LOTO and water conditions for the shootout seem to be flat calm.
First thing to do to change drive directions, is to get into the shifter control box and reverse the push/pull directions for the 2 center drives. Since Skater had rigged the box and engine setup for me, I didn't have any experience with the Latham control box. It is actually a very simple and straight forward procedure.
Here are some photos showing removal of the control box, removing the cable plate rod, and rotating the levers to reveal the correct side access port in which you insert allen wrench to remove cable end screw and reposition cable to proper push/pull location. It was much easier than I thought. Just make sure to protect the console surfaces that it'll be resting on and use a drop of Loctite on cable end screw before installing. Now when I get the drives back, I will have the cable setup ready to go

David, how can you sleep at night .. with that odd cable in there?
Look'n good and your bow lift concept sounds good.

I would try turning motors out. Treating 4 motors as two. Port center and Port one direction and the Stbd center and Stbd as the other.

On my friends 36 they were spinning. Johnny (TNT) said for max speed turn out. We swapped 6s' in parking lot with engine hoist and noticed a 200 rpm drop spinning out at 160 mph. Steve swapped them back to spinning in. To me it was apples to apples at 160 mph. The cat felt light but responsive both spinning in and out and we were in 6" to 1' lake chop. I would spin all of them out to generate bow lift after reading your post. No cat, be it center pod or true tunnel, that I have driven, likes flat water. I will be interested to hear your test results as Steve didn't like how the boat felt spinning out after spinning in for years. Thanks for keeping us posted.

another factor in spinning is docking can be a chore. boat does not want to spin using just engines without a lot of throttle.
Good luck and look forward to the results.

You don't miss much Steve

Thanks guys ill keep you posted

That just goes to show how each boat can be different in handling characteristics. Almost everyone that I've talked has said when it comes to swapping drive direction, "try it and see"

After sleeping on it drive depth may be an issue also with the outboards vs. I/O. I drive buy the seat of my pants in my little Talon. I am turning in on my Talon ,but they recommend turning out. At 160 mph in steves 36 I couldn't tell any diffrence in or out, but we did have some chop to break surface tension. We have chased Bill Plyburn up and down the east coast and blown up more times than I can remember. Bill usually gives us just enough line to hang ourselves. Your the only quad outboard I have read about. I remember seeing Pauls and wasn't suprised when he went back to twins on his 32.

Bob, what's the drive height on your buddies 36 in relation to the bottom of the hull?

He is in England for the D-Day celebration at some castle. I will ask him and get back to you as soon as I can contact him. He doesn't text much and likes to drink alot so....... I tried Friday and got no responce. Will try again now Dave. Check with TZrider (Paul) with the quad 32 Skater as I'm sure he could help. Gary Ballough would be an excellent source of info as Paul and Gary ran his 32 and I bet Gary had alot of input on the setup if he is in country.

For the record Pure Platinum spins out as well as Gary's Yellow 32' and Race boat this year.

interesting, good to know

Paul said he spun outsides out and insides in so I kinda based my first set up try on that bit

Got her wet lately David? I'm talking about the Skater.

Good one Bob:evilb:
I haven't gotten back in the water yet but I'm getting close.
Powerhead came back from Diamond, looks like new out of the box (that's always a plus).
My first experience with Diamond so far, so good.
Finishing up the connections on everything this week, hope to have in the water this weekend, I let you know how it goes

Best of luck David!

Just noticed that David's outboards have a special exhaust on the mids, whereas this 280 engine doesn't

What's the difference in models?
