1998 20hp Evinrude

[Thommo84]

Hi all
I have recently started up my 1998 Evinrude 20hp. First up in needed a new impeller which was easy done. Fired it up today only to notic a crack in the power head. Is this repairable? Or a replacement only item?
also this boat had been sitting for about 4 years

Any crack... even holes can be repaired. Use the gray colored "Marine-Tex". Marine-Tex also manufactures a "white" formula BUT in my humble opinion the "gray" formula is the strongest you'll find anywhere... dries overnight harder than steel or any aluminum. I once, back in 1989, patched up a baseball size hole in a crankcase of a 225hp model with the owners consent, free of charge, (a neighbor) as a test of the materials long lasting capabilities.
I figure it's about due to fail any day now... maybe!

Come on now------That is not a cracked block.-----Most techs know that for a number of years they used too much paint.-----That is just the extra paint that is cracked.-----Seen it many times !

Yeah, I agree... BUT... I just had to give "Marine-Tex" a boost!

Agree with Joe on the gray Marine-Tex. Have used it for many years and nothing but good luck.

Thanks for the replies, I will have another look today. This was mine and my dads boat, he passed away two years ago this Xmas. When I seen that crack in it I just closed it up with out further investigation as I felt absolutely gutted.
Once again thanks!

If it was a real crack up there you would know it instantly while running, either air flowing in or out rapidly or water coming out.
