    Looking for a good rebuilt engine.

    My polaris msx 140 has 110,102,102 psi compression and is turning 6,650 rpm at WOT and roughly 60MPH on smooth water, so im thinking its about time for a engine rebuild this winter. www.shortblocks-r-us looks like they have a good engine but my only concern is that in the desciption it says that they use Platinum Pistons which I thought were WSM pistons. I have heard bad things about WSM pistons so im not sure if that is something to wory about. Another option I was thinking of is a SBT engine but i have heard mixed reviews about them. If there are better engine builders out there please let me know because I want the replacement engine to last a long time. Also the engine has 133 hours on it and was mostly used in salt water.

    I haven't heard anyone having a bad experience with the WSM pistons. Most engine builders use them.

    Contact Jay at Sharp's Marine for a good rebuild. And I believe Short Blocks offer a 10% discount to GH members.

    Have you heard anything about how well shortblocks engines are made? Since you have heard good things about WSM, I may give "shortblocks" a try but Im not sure if the extra price is worth it for a "shortbocks" engine compared to SBT.
