spenaroo Posted October 21 Author Posted October 21 it lives, Took it for a test run on Saturday with my bro, bro-in-law and nephew, the performance was really surprising. we all packed in and it actually got on the plane fairly easily. with a top speed recorded of 54kmh during that run. later in the day when we were playing with it with only one person in at a time get it to 59kmh everyone was impressed, it exceeded our expectations. to be honest I wasn't expecting it to be a great performer, especially with more then one person in it. was expecting it to be closer to a tinny with a 20hp motor on it. 3 1
Litespeed Posted October 21 Posted October 21 Well done Spenaroo. Nice fast restoration. The availability of lots of cheap jetskis makes jet boats easy. If you want more speed just add a bigger bucket of jet ski motor. 250hp anyone? 1 1
facthunter Posted October 21 Posted October 21 I thought it would be underpowered. Props are more efficient. Nev 1

Yes and no, its a whole system that needs to be matched. this has more in it for sure, If I work on the trim of the pump and the pitch of the prop. no point adding power if the prop is already under pitched. but on a whole yes, I happen to know that kawasaki used the same engine mounts through all the 2 strokes of this era... .... so a 1100cc triple should bolt straight in. 1

facthunter Posted October 21 Posted October 21 I am indeed.. Delete reference. I wondered how you would cool it. Nev 1
spenaroo Posted October 21 Author Posted October 21 (edited) one of the great thing about boats is that you have an almost infinite cooling reservoir, its a constant stream of "cold" water, without the need for recirculating it. in this case the cooling is actually taken off the pump pressure, so as the load increase so does the flow. need more cooling, drill and tap another line off the jet pump (common modification, with a second cooling inlet added to the cylinder head for race motors) I remember arguing this point in an old thread about using outboard engines in planes.
