Re: force head gasket

BOB, you gotta look at the exhaust gaskets between exhaust manifold and block. they are a common problem...when they fail the bottom cylinder usually gets wet...have fun they are a royal pain in the arse....

A LOCAL MACHINE SHOP WELDED A ALL NEW ONE IN IT .AND I NOTICE THE BRAND NEW ONES DON,T EVEN COME WITH A DEFLECTOR.BUT I HAVE A NOTHER PROBLEM ,ONE OF THE CLYINDER NO.2 ON THE TOP PART HAS A GOOD MARK IN IT ,ALL OTHERS LOOK GOOD ,I CLEANED IT UP SANDED A LITTLE AND HONED IT LITTLE GOT SOME OF IT OUT THEN I USED A LITTLE J-B WELD ON IT AND SANDED SMOOTH. THINK THAT WILL HOLD UP ,OR IS THERE SOMETHING BETTER.WITH OUT TAKING IT ALL APART.THE COMP. IN THAT CYLINDER BEFORE I TOOK IT APART WAS 125.WHAT DO YOU THINK..THANKS

Re: force head gasket

I have a 97 force 120 well maintained, with only 180 hours on it and I am now in the process of my THIRD head gasket! When I got my boat in 97 I thought I got a good deal my only regret is the fact that I didn't upgrade to a better motor. CHEAP THINGS ARE NOT GOOD, GOOD THINGS ARE NOT CHEAP! And by the way last fall when I blew the last head gasket I did get the head shaved, other then the first year this motor has been trouble! I hear you calling me Yamaha 150!

Re: force head gasket

Bob you had a post on props for your Force. For six weeks I've been shopping for used props and I've ended up three that are different than my 19". <br /> 1 a 17" cupped<br /> 2 a 21"<br /> 3 a 19" four bladed composite<br />So far I would say cupped is worth only 1" more.

Re: force head gasket

Stainless are not a good idea here because everyone hits bottom atleast once a year. I picked up those 3 props used and for the price of a new one.

I wanted to ask tiffany's dream what kind of gas he uses, but he's not a regular.
