Just an FYI....

I just sent my risers back to Eddie Marine to be modified..

They quoted me $350 to change the water outlet to their "water dam" style and extend the inner pipe 3" past the outlet...

There are certain scenerios were a tighter LSA, can make great power on a blown pump gas deal, but this engine build certainly isn't one of them, with a small 177 blower. He cannot afford to throw any boost away with that little blower.

yes it is but my point was that your builder doesnt even remember your build and then just says that it will add 110 hp. engines are complex and if you just go by what someone says every one would have 800 hp daily drivers. so far your builder doesnt seem to have much interest in what he does or what his customers think.

That's cool that they can do that and at a reasonable price. That said, with my original $146 cam it is unnecessary.

You should change the cam, one way or another !

If I have to buy the cam myself and throw it in, I will. Do I have to degree the 134561 cam or can I just bolt it in straight up and go?

You need to degree every cam that goes in any engine. Period!

I just did a cam swap on an engine this week and the cam was 4 degrees retarded as installed. Like vintage said, always degree a cam, way too many possible error points not to verify it is correct..

Sounds great and a good def pic, but too bright for me to see inside. LOL. Can you try another pic ? That would be great as this option may help ton's of people.

I guess 4* retarded would have that exhaust valve closing later, increasing the reversion risk.
