I'm having no luck getting the lower unit gear lube drain plug out. I've tried hitting it with PB Blaster for days. Applied heat. Hit it with an impact driver until the head of the driver twisted around (Harbor Freight...so no surprised). Any guidance on how to get this thing out? Thanks.
I have a 4.3lh mercruiser that I'm trying to get a service manual for. The motor number is OL019867. Outdrive (Alpha 1) is OL0113199. Is service manual number 25 usable, or should I be looking for something else? The boat is a 1998 model year Doral built in 1997. Many thanks.
Here's the situation:
Motor fires up and idles no problem.
Slow to increase up power range when giving it throttle.
With throttle fully advanced, it would not get above 2600 rpm.
Here's what struck me as odd:
I was going over some heavy chop with the motor fully advanced and only at 2600 rpm...
