im new to the forum but have been reading great amounts of info over the years from this site.
ok here we go i bought this sea rayder about 2 weeks ago. took it out and ran it. it was very hard to start but had been sitting for a year or so. while running it the motor just seemed it lacked power and never got on plane id say it went maybe 8-10mph and maybe 4,000 rpm not shure on that. and at wot it smoked a lot more than i thought it should. i have a 3cly 50hp yamaha jet outboard that i compared the smoke to
i took it home and stared checking it out. i check the fuel it looked very dark guessing 25:1 - 30:1 so i drained the fuel and added fresh 50:1. cleaned all carbs. replaced the spark plugs with new. i found a bulliten that has a cross number to a new spark plug that takes the place of the flat head plugs. i installed them. ran boat again it starts great runns fine. but again same power problem and just sounds like the rpm is lower that it should be. i seen the factory specs somewhere and it was saying 5,500 rpm?
engine still smoked at WOT.
i checked the fire all looks good. i checked the compression. all cly's are within the 10% specs.
motor has the red stator.
engine almost sounds like it has a dead cly.
my 50hp yamaha had a loose spark plug wire that would come off every now and then and it would run on the other 2 cyl's but just not any power. the sport jet kinda sounds like that. but with a spark checker all is good.
at this point i am lost and in need of help and help would be great
thanks juster89
