Short answer - no, they won't swap... Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.

It gives me something to scan for on all the various sites such as e-bay.....eventually a powerhead for a 15hp will pop up. Check this box to be notified of replies to this topic.

Will all the powerhead periferals (carburator, etc) from a '54 15hp fasttwin fit onto a '56 15 hp fast twin powerhead. I have a complete '54 with an unsavable block. Found a complete '56 powerhead advertised with good compression. Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.

Not quite. '54 and '56 had significantly different mid-sections, which makes the powerheads not-quite compatible. You need a '53 or '54 powerhead to make it work.

What, exactly, do you need to make your powerhead complete? I've got a block and some other bits & pieces at the shop for a '53/'54...

Well, the block, crank, one piston/rod/bearings are all toast. I took them to a machine shop and the guys siad they couldn't be saved. In a different thread (scrape yard evinrude) we talked about the parts you have and a friend's block. But I dont want to put any serious money into this motor. Hoping to score a compete powerhead. The one I was considering above is a '56 selling on ebay for 50 bucks.
