Re: 1989 yamaha 150 head gasket replacement
Engines are twins on a contender 25, both powerheads are in excellent condition. Compression is strong @120 lbs each cylinder with no delta (PSI). Plugs are burning perfect with no sign of water contamination.
Broken bolts ... you are not kidding .... been there .... done that ... I am replacing the steering arms and the shift shafts on both engines. Yes, I went through the cruling fiasco of having to cut through the adapter plates to cut through the bolts to free both powerheads.
The rest of the engine is in close to perfect condition, amazing. I ask about the head gaskets to take as much preventative maintenance precaution as possible without getting in deeper than I already am. I will be venturing way offshore and want to have some sense of security.
I was contemplating opting for repowering with DFIs but I do not have the budget right now, unfortunatley.
Estimated parts so far ~ $1,800.00.
Your thoughts!
Thank you for the prompt reply.
