Just changed the impeller on my engine and the water is pumping well now. Only problem is I need to get into the saltwater/fresh system to replace the filter. The cap will not for the life of me come off!! Its the big round one on the left (not the radiator side) I have attempted to get it off much to my disappointment, it only should need half a turn then come off right? Any help would be appreciated. Its a new boat i have purchased and just doing all the things so she runs mint. Thanks
It sounds like the seal in the cap needs to be replaced.If not then you have something plugging the system causing it to build up too much pressure.
You need to push down on the cap before you turn it. The water strainer only needs to be cleaned from time to time. It a plastic basket type filter. These are great running engines. Good luck! EDIT/ No the cap should be OK. Impellers last 2/3 years on average. The water filter strains out stuff that could plug the system. I clean mine about every 20 hours of use. It's easy once you figure out how to get the cap off. I'm glad I was of some help.
