Does anyone know how much HP the old style ( early 80s) mercruiser engine coupler will take? I toasted mine and not sure if I need something heavy duty or not. I'm not over 400 HP but maybe close to it. Thanks for the help

They are good to about 350hp and can handle a bit more if you don't completely abuse them. The old one most likely failed do to age as well as hp. Cool

Hey thanks a lot for your help I did order a new coupler from sierra marine so will see how long it lasts. Do you know is there a heavy duty option for that engine set up ? The drive is alpha 1 gen 2 Shocked

Sorry there is no heavy duty model. The heavier ones are for a big block and won't fit your flywheel. Cool
