Pin hole in water jacket
We have a large model 1980's-early '90's Yamaha 115 2 stroke on our flats skiff. Yesterday I discovered a hole about 1/16 in diameter in the water jacket behind the thermostat housing. Ant one had a similar problem? Will JB Weld fix it, or do we need to get it welded? It's located in the block, not in the cylinder head housing, it's not a bolt on piece. No I'd tag on the motor, so no further info on model, except it's a 20" shaft.
