i just watched my video again and i will say that the vibration is way worse than the video makes it seem. its mostly at 1/4 throttle. low speed jets ill swap this weekend, and pop off ill adjust when i get low profile FA's i got the high speed tuned in this weekend. it runs best at 1/8 turn...

lol sparkplug i like your enthusiasm.... but......... as i already mentioned (please read entire thread).... the engine was not fully tuned in the video. when i inquired about the insane vibration, i was told by many many people that thats how the rhaas motor mounts are. this vibration pretty...

oh yes and has anyone stripped out any motor mount threads on the conversion plates? they are less then 1/4" thick i believe, and have aluminum threads. so you grab like 4 threads at most. there should totally be a steel thread insert. one was stripped when i got the plates, and upon final...

welp..... got mine in the water.. the motor runs good but the vibration at off idle to 1/4 throttle is so unbearable that i consider my jetmate to be pretty much out of order. i usually send my mother sister girlfriend and guests out in it, but i will not be. apparently this is "normal" with the...

thanks for the responses guys i didnt have directions for the Rhaas kit because i got it used. but they say it works on the jetmate. it can work on the jetmate but its pretty bad marketing considering they never even tried it, dont have any pictures, and it needs lots of modification to work...

i still need an exhaust system if anyone has anything for sale that will work

these are the rhaas mounts that are milled on the bottom. i got it much closer but had to do a lot of finagling. there is play in the motor mount bolt holes. the left side mounts had to be pushed all the way out plus a good amount of shims. the right side had to be pulled all the way in with no...

well im not too pressed with the plates. the same goes for the support i have gotten from rhaas. these first 2 pics show how the plates interfere with the oil tank bracket (battery and ebox bracket for me) this one shows how badly it interferes with the exhaust tube. hopefully turf will make...

1. the conversion plates sit on a flush surface, so the motor mount bolts must be exactly flush with the bottom of the conversion plate. i cut my bolts to the exact length so thats OK. 2. the left side conversion plate offsets the motor mounts wider to account for the wider yamaha bed plate on...

hi guys, im in the process of swapping my jetmate to a yamaha 701/760 motor. i ran into a few small issues and tried to find some pics of other peoples swaps. i had no luck... has any one done this??

short verison 13/18 prop cavitates down low, slow acceleration, and slow up top (not max rpm) long version i saved a 750 BP motor, lightened flywheel, B pipe (center bleed style), dual kehin carbs, 750 ebox, and pump (with 13/18 KA-SC-I Solas, AM cone, and some sort of reduction nozzle...
