    5.0 to 5.7 350 Mag Swap worth it?

    So this spring I bought a 2007 Chaparral 246 (4200lbs empty) with a 5.0 and Alpha 1 Gen 2. I knew it was going to be under powered but the boat is super clean, EXACTLY what we were looking for (except power) and it was great deal so if I had to put money in, Id still be inline with values. After...

    2006 Chaparral 246 prop change and max RPM drop (videos attached)

    New to us 2006 246 SSI (4900 lbs) is under powered with 5.0 / Alpha. (this will change!) The SS prop it came with was in bad shape, mainly a few too many back yard strip and repaints. No way to tell what it was besides being old and aluminum. Here is a video with the old prop. 5200 RPMs best...

    New Solas fixed hub not fitting.

    Just upgraded to 2006 Chaparral 246SSI. I wasn't happy with the hole-shot performance and the aluminum 3 blade was in really rough shape so I bought a Titan HR4 SS with fixed hub. Drove over to sand bar and tried to do swap in 3-4 feet of water. The prop is under a swim deck and completely under...

    3.0 popping breaker (I think) under load then not resetting / restarting.

    1996 3.0 in 18' Sea Ray. Been having intermittent issues for last two weeks. Starts and idles fine. Runs fine going slow. While running at 3800-4000 there has been random, very quick RPM drops.
