550 engines

[Jakew]

I have a 2003 550 and I am wondering are they really that bad

[loosetrack]

bad in what respect????????

[Jakew]

I mean in the reliability aspect

[jdvann]

My 2002 550 has 11,000 on it...use to be a Yellowstone rental, don't know the total history though. Is still reliable.

Do u think it worth while to rap insulation around my exhaust pipe to reduce heat goin into the cooling intake

[FrankieJames7]

was woundering the same thing

[Jakew]

I heard it may work

[FrankieJames7]

ive heard in the edge its because the fan air intake is so close to the exhaust the engine is really hot all the time...wiesco pistons a little rich jetting and turned up oil pump should get you by with out problems

[Jakew]

K sounds good

The 550 is a gutless fuel hungry engine that is almost impossible to be a "finely tuned" performance fanner. A yamaha 485 Phazer had twice the "Nut" than a 550 Poo. But, jetting it down and wrapping the pipe will help a bit.
