1999 Yamaha LS2000 Jet Boat with four stroke engines

Description

Originally it was regular Yamaha jet boat with twin 135HP two stroke engines!
I don't like two stroke motors, and I had idea convert boat under four stroke motors.
Soon I have bought on Auction two Kawasaki 12F jet ski in salvage condition, BUT with 47 hours on engines ONLY.
Day by day I adapted these engines to Yamaha hull. There were a few major problems, but everything has been solved finally!
I have replaced everything I could on stainless steel, new set of gauges, new battery, mass breaker is on dashboard, new air and water pumps and et al. Jet pumps are in good condition too.
Boat runs smooth, quit, fast, power, and good on gas now. Exterior/interior is in 8 from 10 condition.
I redone rear seat and replace front with Honda leather powered seats. There are bimini top and cover.
Trailer has new wire, good tire and bearing.
There is new Sony CD and Speakers.
Why I am selling that boat?
It's speed boat! It is very good on 4500 rpm and higher, has very easy, fast and stable plane, but not so good for slow ride. I am old man, and speed is not my priority.
Thanks for looking
