Model 25924 is a 1956 30HP, What66.<br /><br />You might have a patchwork 'Rude made out of several similar engines.<br /><br />Champion J6C at .030", points at .020".<br /><br />Fuel mix is 24:1.<br /><br />Good luck.

I think it would so long as you're talking about a 35hp without a thermostat. That is to say a '57 or some '58 35hp engines. The thermostated engines have a round base that's incompatible with the '56 base.<br />There may be some issues with the brackets and such for the cover. Not 100% sure on that.

Re: help identifieding old evinrude

well yes it is without the thermastat.<br />I want to use the 30 head so I don't want the compression reliese.<br />I tried the head and it seems to fit fine.

Re: help identifieding old evinrude

just for any one that wants to try rhis no a 30hp head will not fit a 35.

What was the problem?

Re: help identifieding old evinrude

I think we're speaking of a cylinder "HEAD", not a power "HEAD".... A 30hp cylinder head will not fit on a 35hp powerhead - different bores...<br /><br />If you want a cylinder head without the compression release that will fit a 35hp, look for a 1960s vintage 33hp cylinder head...<br /><br />- Scott

Ooops! Sorry about that. I was somehow thinking "power head".
