my old school build
I bought an bullet marine race hull from a friend in Oklahoma. It was a mostly bare hull and hadn't seen the water in a long time. I was told it was originally built for the "800 outlaw class". At one time it had a lamey cylinder 62t setup and was part of the riva race team.
My original goal was to build a twin pipe 66e motor for this hull, but it turned out my pipes didnt fit because of the custom bottom deck. The bottom of the hull is very similar to seadoo in design.
Shortly after that discovery I came across a very weathered 1100 waveventure with only 52 hours for $1000. So now I will be running a 1100cc triple in it to save time and simplify the build.
Future plans include adding 44's, boring to 1200cc and porting the motor. However for the first water test it will be a 1100cc stock motor for baseline.
I'm trying to build an acceleration machine.

First order of business was to move the front motor mounts forward. I couldn't move the rear ones back because of the custom driveshaft ( i didn't want to have another one built).
701s, 66e, 65u, all have the same center line so by moving the front motor mounts forward alignment is still perfect.
Luckily the hull had aluminum plates in the stringers so i just had to measure, drill and taps some hulls and the motor mounts bolted right in. Picture shown had the orginal 66e motor i planned to use but didnt. The 66e motor and the 1100cc motor have the same motor mount placement.

The venture had a very small opening to pull a big motor out of. If i would have had a sawzall, i could have saved about 2 hours. If any body needs any venture parts I have quite a few left over.
Pics of motor installed, driveshaft came with it (luckily), its custom and uses a similar setup to seadoo. The coupler is a seadoo pto with thats been turned down and threaded to accept the yamaha crank.. The motor sits back quite a bit further than a stock gp. Should hook up well.
