I need to replace 79-(228) v-8 with ?

[osborne looney]

i am kind of new to the I/O'S have worked on plenty of outboards -- i just picked up 79 century 20' with a pretty badley cracked block (both sides) from ice i would presume -- from what year to what year can i replace this with little as possible ? also can i use a higher hp 6cyl ? 190hp they seem to be more available for some reason any help would be great thank you

We need to know what the current "cracked" block is. The outdrive you have is likely geared for a V8, going to a V6 might require a different outdrive ratio. You don't want to drop down to a V6 anyway.

cracks are beyond repair i believe cast is pushed out in a circle or horse shoe about 4" diameter so i guess i will look for a good 228

Easiest solution is to replace with another first generation 305 - or even 350. Keep it to an older two piece rear main. Be sure to check the condition of the manifolds and risers as well.

The 228 was 4bbl Chevy 305 I believe. I would replace it with a 350 since it's almost a direct swap, parts-wise, and you'l get another 30-40HP in the process.

If you have good accessories that you can transfer over, then a universal crate engine is a good deal. You can transfer your marine externals and are good to go. I believe these crate engines even already have brass core plugs and composite head gaskets - but you can check. You can get them various sites for around $1,500. Here's an example.

As mentioned above - get another engine with a two piece rear main - basically anything before 1985.
