If it's wired correctly. turning off the battery switch will not prevent the charger from charging the batteries. Not supposed to be set up that way. And the bilge pump should go directly to the batteries also.
I'll put some seafoam in the oil and run it for a bit. Change it out and it help alot. I'll use cheap oil for the initial changes and then the correct oil for the last one.
Sounds like you need a smart charger. They moniter each battery sepratley, and only charge/maintain each battery. Them old school chargers don't care what they do to a battery. They will pound out amps and burn up the good battery if the other one is weaker. It is recommended to replace both...
You put a piece of tape on that open wire to keep it from shorting while you are working on it. open up the dash panel and carefully pull it out and look very hard at all the wiring under there.. I've had success with a selfie stick under there and getting some pics with my phone to see what's...
Good Marine mechanics are getting harder to find. Sound's like your mechanic needs some schooling. Spark, compression, fuel. Just have to know when it's all supposed to happen in the right order.
No macerator pumps on boats that are on fresh / inland waters.
There are plenty boats in fresh water that have the macerator . They have a "y" valve inline, wich if in fresh water must be locked in position to not allow waste to pump overboard.
What alldodge said, I usually take a good flat screwdriver and give it a rap with the hammer, Works most of the time. replace the screw with one that has a better groove, and the gaskets at every change. Some of them are stubborn.
Are you sure there is no primer? Had a similar situation with a customer. Their motor quit just outside the marina, they were pinned against the breakwall in some rough seas. I dashed out there and their fuel pump had gone south, I dug around and found the primer bulb way down in the bilge...
If you have a big plot of land, and young children, you could strip it down to the basics, bury it to the waterline, put a sump pump in it, and a pole building cover of some sort. It would make a great playhouse for the children. Nothing more.
Of course they will fix it. They just want your money. You really need to check further for any damage inside, it looks like it's been that way for awhile. Any flotation foam is saturated. You won't see water in the bilge till it gets through the foam.
My duckboat has .22 caliber holes in it. The po had simply put ss bolts in the holes with sealer. I bought the thing from him 35 years ago. Gives the boat charter. I still might fix it but it don't leak.
