I have bought 2 jetskis with new motors from SBT. Both of them with serious issues. First one had low compression in all cylinders. Second had a gouge on middle cylinder block and was leaking water and after having it fixed, the third outer cylinder piston fell apart........... The warranty seems impossible to hold them to. Pay to have your engine rebuilt locally so you have some sort of guarantee.
