    Default Dominator bowl detailing

    I am in the process of rebuilding my late model dominator 12S and have some questions. I found out why I got such a deal on aluminum jet boat as the previous owner sucked up some rocks and they were not nice to the impeller or the bowl. I intended to replace the aluminum impeller with a stainless one so it didn't hurt my feeling when I found chunks missing from the back side of the impeller. The bowl has a few dings on the leading edges of the fins. I figured that it would be a good time to detail the bowl. In all my research it seems that everyone just sharpens the fins but I feel that smooth flowing profiles disturbs the water less. What should I be striving for? Sharp or somewhat rounded.

    I strive for a "butter knife" leading edge a razor edge will work better but deforms and causes turbulance

    There is a lot more to detailing a bowl the right way then just sharpening the edges. Extrude hone takes it to the next level.

    Who does extrude honing and what does it run for a bowl?

    I really cannot justify that for a fishing boat. I guess i'll just clean it up as best I can with a dremel and hand sanding.

    For most things the impeller or bowl box stock is usually pretty good. I've seen plenty and tested a few "detailed" parts that were worse than the factory casting. Jack at MPD can get stuff extrude honed for you. They come back like someone polished the inside all the way through even in the places you could never reach with a hand tool.

    Agreed, for your purposes a bit of cleanup with a die grinder and rock it, the gain wouldn't be worth the investment , spend that extra $ on beer and tackle

    Beer and tackle it is. I'm sure that the work I have done to the bowl will be an improvement as I basically just cleaned it up and removed the casting flash.
