I bought his engine about 3 years ago and have not had a chance to get it up and running. Firstly I discovered leaking seals in the lower leg, which I fixed. I replaced the impellar and water pump housing and got her running nicely for about 30 minutes out on the water. Then she died and although I can still start her water gushes from around the sparkplugs. I'm guessing the gasget in the water cover of the powerhead has gone. So I attempted to remove the bolts and of course they are all corroded so badly the top 4 just brokeoff so I will have to drill them out. After a lot of hassle I have removed the 8 bolts holding the powehead on to the exhaust housing but cannot budge it. The cowling makes it very hard to access the gasket join or indeed to achieve some sort of purchase to jolt it free as the manual suggests. I have no hung it upside down and applied pb blaster where possible but still to no avail. Any ideas on how to seperate them wold be much appreciated. From down under, Martin
