thanks for the advice guys

i'm looking at an '07 avy with 130 hours and the black scorpion. would you get a compression test on a motor that has that low of hours, or lake test and decide from there? if not, at what hours do you start thinking about confirming the shape of the motor with a compression and/or leakdown test?

more weight!

also interested in pictures and details

wow i love the look of that, great choice!

i've never been a fan of the older MB graphics--flames are a love/hate thing. they are good boats however, but i'd probably go centurion unless you don't get a good feeling about it once you go look at it.

Here you go...no ballast in this pic, 25 mph. I was a little heavier on the driver's side hence the wash to the port side.

i can take some tomorrow when i go out but, it doesn't interfere at all with the wakeboard wake. i also added a surf flap this year to knock the spray from the exhaust down at surf speeds which helps both the surf and wakeboard wake.

thanks, PM'ing him now.

thanks bomoseen, that's very helpful.

2006 is when they went to the 1.46 ratio from what i've heard

Example I pulled off the web....those drain holes don't look like there's much room for enlargement to support a bigger pump and hoses.

In the various upgrade threads I've been reading I haven't found anything that answered these questions. The Avy and the Tige 24V are the two possible boats that I'm looking to upgrade to next, and I know the older versions of either of these boats (I'd be buying 2003-2005ish to stay in my price range) have small ballast systems stock. With this in mind, I came across an '03 Avy ad the other day and looking closer at the stock ballast drain location on the starboard side it seems that the 3 exit holes are really close together. If I was going with an aerator pump upgrade instead of switching to an impeller system, is it possible to enlarge those drain holes to support a bigger pump and hose or are they too close together for that? Additionally, would it just be plug-and-play to swap in new bigger pumps and hoses re-using the stock switches or are electrical upgrades needed to support that as well? I'd be wanting to go with Rule 17A (3700gph) pumps to fill the Enzo sacks that would be installed.

here's a couple that i found before angling the exit tube much like yours. i think you will have an easier time getting yours to stay on--mine took a couple tries. similar to your rivet idea, i drilled pilot holes and used stainless screws through the exhaust exit ports, as well as attached a reinforcement to my trim tab. one difference i see is that i used leftover rubber exhaust manifold tubing for the first 1' or so off the boat.

awesome! i did the exact same thing out of abs last spring and it worked great all season. no issues with the heat of the exhaust water--keep in mind the boat is sitting in the water when running so the lake water cools the exhaust too. but even when running on the hose it doesn't even get hot to the touch. nice fab work!
