1st off, I just found this forum... I'm thrilled to find a site with so much info. I'm also a boat owner newbe, I'm restoring an early 80's Sylvan deep V with a broken Merc Thunderbolt. I actually know this boat's owner so it should be a good project when finished. If I can find the parts....
I have a 1977 Thunderbolt 50hp 4 cylinder, the seals were bad from the former owner and it froze and poped the prop. Does anyone know what years will fit this? I am hearing that any "Thunderbolt" lower unit or case will fit, do you agree? I have been looking at Ebay but noone seems to know if theirs will fit when I do find one.
This motor has the mid section, then a 3-4" spacer piece, then the lower unit, I'm being told that this is unusual??? The s/n shows the motor as always being a long shaft.
This lower unit also has long bolts sticking up because of the spacer. If I find a short shaft case or one with the short bolts, is it just a matter of transfering the longer bolts?
My lower unit guts are good, I really just need a case and i'll have some seals thrown in it while it's apart. Any suggestions other than Ebay?
