Stainless marine exhaust and got rid of a crazy rich tune up, also quit using non projection plugs because they foul out with aluminum heads. Not enough combustion temps.
Loaded in ZP's tune up and it just made a **** ton more power!! Bolted on ZP's props now I cruise at 60mph!! |

Anybody that thinks its a lie, put some money where your mouth is (we now you guys have a mouth, not sure about money). We will install them and go collect my money!!! I really do think these boats are extremely sensitive to prop blade design. It's damn near impossible to know what you are running. It's either trial and error, or owning a blade scanning machine.... I can't afford to go through testing props at $3K a whack, it's frustrating. |
I don't know why anyone on this site would build bigger motors if they were just going to blow out the props at cruising speed and go slower on the top end .:evilb:

Holy ****, 70 @ 5000? that's some serious slip if you are running 925hp.

Sucks to get slammed after drilling me all last spring huh? Man for such a perfect builder you seem to have many issues going on. I love it... You told me I was stupid and can't build at all, you were so perfect... Guess not... And so far my slow tird is faster then yours this year love it!! At least I see 73... Haha

Interesting. I have been running non projected tip plugs for years in aluminum heads, never had one foul. Bunch of guys up here running icy cold great lake water thru their engines, with no issues. You sure it wasnt your rotor that was welded causing fuel distribution issues fouling your plugs ? :cartman:
