update:

ben working on it a lot lately. got to start it up last weekend!!! :cool-smiley-026: I ended up having to pretty much pull the whole interior apart. the wall between the cabin and cock pit was only attached with two screws on the bottom. I think the build quality on these small boats aint as good as the bigger boats.

after I started it I had a few coolant leaks. take a look at the clamps I bought I though they would work better than worm gear clamps but I don't think they do. they leave a small gap right under the bolt of the clamp. im kinda worried this thing isn't gonna be reliable. I think I spent to much time making it look neat rather than function/ longevity.... after starting it the cam sounds a bit more radical than I expected. im worried about water reversion. I need to pull the exhaust off and check. .... please chime in with your opinions on any thing you see that I could improve.

I made this harness for the engine. FYI if any one does this and has the msd box up in the dash yr gonna have to make yr own extension harness not hard just tedious. you can get the plugs and terminals from eficonnection.com. if you do it like that it will leave you with 3 extra spots on the engine side of the harness. tach ( because that wire will come off the 16 pin plug on the msd end of the harness) and yr 5volt supply and map sensor signal cause you really don't need it. so I used one for starter solenoid, and one to excite the altenator. and then one spare. that way you got one nice clean plug for every thing on yr engine.:cool-smiley-026:

I had a friend make this water neck so plumbing to the heat exchanger was easier. I cut the old one out and pressed this one in. no leaks so far

Your speed numbers sound way too low to me. I had an 86 scarab I which has a different deck than the later excels but same hull I believe. It ran low 60's with a 454/330hp, mirage 21p 3 blade and alpha 1.5 drive. I also found an old PowerBoat report on the Excel that tested it at 58-59 mph with the standard 350 mag so I think my non-GPS speeds are reasonable. I ran that boat for 10 years with no drive issues and that was a 454 BBC. I did add a stern jack later on and an alpha ss 1.32 gears and got it to run about 70. Stern jack and standard alpha ran high 60's.
The LS must be lighter and more HP so your boat in my mind is a 70+ mph ride??? Interested to hear what you find when you get it dialed in.
