Had no luck with my searches anybody know of some place that has these parts ,used on the head would be nice. Even to find the specs seems to be a chore also.

    You anywhere near Grand Falls there Carner Boey sort of figgered you were from the rock with the name you use Just kidding about the newfie part as you know,I have many relatives there.Maybe you should change your profile to say your from Newfoundland Canada and show your proud of the place as most natives are.Shoot me an e-mail so I can hook you boy's up.........And hystat that,s a great offer it's up to the nephew the bucks are low with the new baby on the way

    The head is off a block that split, I had the engine running even with the crack in the block, so I think its good...I live in Torbay and am having my own troubles with my pre-Alpha out drive...But what ever the thing is worth I'll take...What is wrong with the one you got now?

    Not sure what's wrong with his as the boat's in Grand Falls and I'm in Ottawa ,he just left after a visit here.He took it in to a shop and they told him the head was cracked .Compression was 90,40,40,100 which sounds to me as just a shot head gasket with two adjoining cylinders being the same #'s. Is the water in the ocean that cold it,s spiltting blocks and heads

    I purchased my boat in Richmond VA and brought it to a garage in OH, I do alot of traveling, The guy had his own boat and I asked him to winterize it and he said he did, the next summer the block was cracked...a tuff lesson learned...
