1987 Merc 45 classic 50 bogs down.

[thomas_e102]

I have a 1987 merc classic 50 45 tiller that bogs down after about a min. at WOT. I give it a few sec break and I can go WOT for an other min. If I prime it while it begins to bog down it has no problems. I the changed fuel, fuel tank, line, and fuel fittings. Starts and Idles just fine. What do you think.

If you pump the primer bulb and it saves it, i.e. it stays a WOT, then it is definitely your fuel pump. It is an easy task and cost about $8 for a repair kit
