So we toddles down to Batemans Bay looking forward to some fishing and clowning around, we launch the boat no probs here, I prestarted it on the ramp before dropping it in the drink, loaded it up and off we go Im thinking Hmmmm this aint going real quick and why is it not coming of the plane tacho is showing 2800 flat out, this isnt right so we turn back I beached it at the ramp popped the engine cover off and theres a plug lead off, couple cable ties later were off and its fairly screaming at a tad over 5000 RPM much better, stop a little ways up the Clyde and sat about drifting with the tide hoping to snare a flatty or two, was getting a little close to the oyster plots nearby so fired it up to move, same prob wont rev over about 3000 and wouldnt come off the plane so back in again we went I was royally cheesed off by now and decided to call it quits for the day pulled her up on the trailer popped the plugs and shes holding about 80 litres of sea water in the bilge.
I narrowed the leak down to the crappy little plastic pieces the plugs screw into, had a further issue with the trim not operating when running but u can stop and when idling it will raise and lower fine, it had a creeping issue but after a blee dof the hydraulics its not creeping, not being able to trim it is a pain in the bum, anyway I drove around the Bay and found an open boat shop got some new plugs and chromed brass bases and some silicone I changed the plug sin the Hotel carpark, bled the tilt hydraulics, fitted new spark plugs, checked the gear box oil, put it in Satdy morning, no better no power over 3000 RPM and the volts gauge is only showing 12.5Volts at cruise, not good. I doubt its the regulator, its running a car battery of about 380CCA, I know car batterys in boats are a no no as outboards need a deep cycle battery with high amp hours, could this be affecting the power output? could there still be air entering the fuel system and the not being able to trim the motor biz at cruise? any ideas ? I have bought a bilge pump and flipper switch to activate it, we still got some water out of it after replacing the plugs so Im guessing theres a split somewhere I looked at the rubber strips on the trailer skids and there hard as rock so maybe its rubbed through the hull above the the skids Ive had this happen once before with old Pride hull, so Ive got some work to do, appreciate any advice on the other issues with it.
