Belt tensioner wheel for LT-1 and LTR marine engines.
Fits on a 2002 Maristar with an LTR engine. All pulley's lined up. These do wear, I'm on my 3rd one since the life of the boat. Had to change alternator, so did belt at same time. I believe releasing tension on the belt thru this part caused the part to break, hence needing a new one.
Part is well manufactured and appears to be high quality. HOWEVER, it is not as pictured. The frame is a single flat piece of machined metal. The shoulders around the bolt holes are not present. This makes the thickness at that point nearly 1/8 of an inch less than the original. As a result, the original SS bolts bottomed out on my Indmar engine and I needed to purchase shorter bolts. Washers could also be used. Otherwise a good piece.
