Raw water coolant hose to velvet drive trnansmission cooler

[TomA]

My friends 28 TE has a 6LP-STE, with Velvet drive tranny. Raw water inlet hose to the tranny cooler is ruptured and the local Yanmar rep is having a difficult time finding a replacement. The end connections of the 90 degree hose have different sizes 2" hubbed ID outlet vs. 1 7/8" straight inlet so a stock replacement hose from an auto parts store will not work. Anyone had to change one of these hoses, Yanmar PT# etc.? Tom

Firstly, it's not listed as a yanmar part - you should be able to find something in an auto parts store.

Secondly, and possibly the important bit. Are you sure it's the inlet and not the outlet side of the cooler? If it is the outlet, your intercooler tubes are almost certainly blocked solid.

As you know the engine is reversed and therefore it is on the starboard side of the boat. besides I took of the hose on the other end of the cooler and it had some build on the interior of the hose but not enough too block anything.
