    Camshaft for mercruiser 383

    It looks like we will be replacing the engine in our boat this winter. I am weighing the options of how to proceed. One option is to rebuild the current 350 Mag MPI into a 383. Due to very limited tuning options, I want to basically recreate the drop in 383 offered by mercruiser. Can...

    Water in bilge

    I just got a new to me 2006 Crownline 240 Ex, 5.7mag MPI and bravo 3. After 2 times on the lake for a few hours each time, the boat is getting a decent amount of water in the bilge. I am planning on replacing the bellows next weekend when the parts get in. While I was waiting, I pulled the...
