anyone have experience with them? Ive found a spare block and would like to rebuild it to keep as a bolt on spare for my guiding business. The motor is a 1984 johnson 75 hp.

Ive found two OEM pistons, but havent been able to locate a third new one.

The WSM are readily available. anyone have any experience?

I've run WSM in my personal and in customers motors with no problems... I'd say their about the same as OEM when it comes to quality and durability.

made in china crap,put them in a 70hp omc and a merc v-6 150 after a few minutes running the pistons ate them selves up.Tore both powerheads down and the whole in side was like alumamud these motors never even hit the lake.NEVER USE THEM AGAIN

That's a double shot of real bad luck! Must have been the real imitation knock offs .
