If I'm reading this right (had a beer or two) you have a decent midsection? Other thing to check is the earth straps - my old yam 55 had a broken one that killed the powerhead and ultimately led to me totally rebuilding a merc clamshell. But that's another story....
Both Davie and Yampower have kept me going. I big both of them up. Seriously.
reckon you can go one of two ways- either get what you can back from the original deal or go for a rebuild which will give you a relatively known engine.
Hazards of old oil burners....
Hi yeah, great mid section.
2 of the 3 earth straps came with the new section already attached, the third one, up at the transom arms, just needs reconnected.
I've started the slow process of getting both mating surfaces clear of old gasket and was wondering if anyone has any tips for getting a nice smooth surface, some alloy friendly gasket goo eater?
Also, would people recommend using a gasket sealant or grease for the powerhead gasket?
And lastly, does anybody have suggested torque settings for the powerhead bolts when putting them back in.
Thanks again guys
