Mariner 4hp outboard can't get engine off casing

the drive shaft goes down through the water pump impeller and I suspect that the problem will be in the pump the impeller is rubber and if run dry will melt the rubber into the housing and bind up the shaft Brute force is a last resort so get all the information you can from a service dealer mechanic

Having trouble with my 1974-78 outboard marine engine

Just an idea but your water pump is only rubber and setting for the winter it didnt stick to the sides of where it pumps did it.. sometimes these pumps are tempermental.. you might check your water pump again making sure its pumping right.. is it peeing out the sides good like it is suppose to ? also if its getting hot on top it makes me think the pump is not doing its job right maybe just pumping some.. not enough? just a thought .. thanks Jerry

I have a Mariner outboard

In order to disconnect the gearshift linkage from the gearshift operating handle, a safety clip was rotated about 90 degrees clockwise. Once in this position, if you pull the safety clip towards you, it comes completely out, which then permits the gearshift rod to seperate from the operating lever.

My 2008 Maringer revs wide open at start up, so I shut down immediately, why?

Throttle body may be stuck. Spray come cleaner into it. Also a large vacuum leak will cause a high idle.

Mt Mercury merrinerr the rpm Gage keeps going up and down now a wrench light has come on what might it be

Hello...In order to isolate the problem the "wrench Light" is indicating a fault code has been stored in the vehicles computer. The first step to determine what the problem may be is to retrieve the code(s) via a ODBII code reader. Some parts stores offer free code reading so check with your local Auto Parts retailers for this service.
