i just removed a factory belly tank from my 81 islander. It is possible the tank might have been replaced but I say it is factory because it was built the same year as the boat! it is 50 gallons and there was a vertical 2x4 in the bottom of the hull and on top of that was a 1/2 board as long as...
Hello I just picked up an 81 Islander 22ft V5 outboard project boat. I was complaete and decent, but the stern corbers of the floor were rotted.. pretty cool, as it came with the original Float On dual axle aluminum trailer with TORSION springs.. and the original 1981 Johnson 150 hp Seahorse...
not specifically because the 12 gallon tank is full right now...BUT the motor starts and idles perfect... and when I take off initially with the boat and can get up to 30 mph and run about 4500 or more rpms for almost 1 minute...THEN the surging starts.... would the water in the tank PREVENT that?
So no one is mentioning the fuel pump itself. Is that likely to mean surging isn't caused by a bad fuel pump....or surging isn't a symptom of a failing fuel pump
ill try that
That's a good idea but logistically it's difficult,because my issue arises when trying to go over 3000 rpm AFTER about 45 seconds. It doesn't surge at idle or below 2000 rpm. So to rig a tank and hose and a temp line, then take the boat out on the water...doable but not easy alone...
brand new impeller, the kits are superceeded and cover a lot of modles. Paperwork says you dont need some of the parts(o-rings) even though the original factory manual says use them.... the tell tale is shooting 8 feet in a straight line!.... Im wondering if I have blockage in the head itself...
I have a 1996 johnson 70 hp. It started surging about 4 trips ago and it seems to have gotten worse. I have a new moeler 12 gallon tank(actually used last season too) its direct plumbed to the motor cover where there is a j-e connecter. It has 3 year old fuel line from Shields A1 premium fuel...
