oups.com: If we're leaking into the crank oil it isn't raising the level noticeablely... The old 4-108 Lionheart came with had like 9000 hours on it and little maintenance. There was a good bit of unburned diesel oil leaking past the worn-out rings, but it just ran and ran. The current engine was a pullout from a nice fellow (who may be watching this...(c ![]() NC. I met him on this newsgroup and my captain/owner bought the engine/transmission from him for $1200, I think. Lionheart's original transmission is the hydraulic one that can freewheel forever because Lionheart has a shaft alternator producing 15-20A of charging current at 8-10 knots off her fixed screw. The more recent transmission was not, so the engine ship switched them. The old engine is in Marietta, GA, in the captain's garage, last I knew. He was going to rebuild it, but hasn't. They're great engines. Ours flooded 3 of 4 cylinders with seawater between Ft Lauderdale and Ponce Inlet to Daytona when it was locked up, solid. Towed the long way to Daytona Marina up the ditch, Cutter Doc was hired to fix it and he came that night to pump the Exxon Valdez oil slick out of the Perkins' bilge. It had tar balls in it! One injector mount was cracked and 2 injectors were trashed. We changed the oil a "few times" until pumping it out looked something like oil, then reinstalled the injectors and she cranked right up. It's been running flawlessly ever since. The new engine had nicer controls and working guages, too. We can even read oil pressure and water temperature, now...(c; Reliable old tractor engine....English like my captain! |

Geeze, I've spent more than that on parts for this sucker and it only
has two cylinders and 1200 hours... If I cut the decks off and took out two structural bulkheads, removed the galley and shower and removed a lot of weight from the boat so it wouldn't sink (no problem there, I'm pretty sure the better half would leave somewhere between deck and galley removal and take all her stuff) I could install some 4-108's where my little 2gm20's are. This would solve the hunting problem... Thanks for the thoughts Larry, -- Tom. |

This would solve the hunting problem... Thanks for the thoughts Larry, The old boat, now called "Stray Dog", has a 2GM20 in it. When I took that one over it kept loosing the closed loop coolant. The Japanese geniuses hooked the recovery hose to the CAP of the recovery jug, a separate plastic jug mounted on the bulkhead by the engine. Noone ever looked inside the heat exchanger. They saw the level in the jug and everything was fine...WRONG. Stupid design. The pickup hose INSIDE the jug from the bottom of the tank to the cap had fallen off...allowing the poor engine to suck AIR not coolant every time it cooled off! The heat exchanger was nearly dry! I dumped the stupid design and bought a universal replacement bottle with the hose properly located out the BOTTOM of the jug from Autozone (geez, don't tell anyone at the yacht club bar!) and that solved the coolant leakage problem. I suppose it's cheaper to put the recovery hose in the cheap plastic cap than have to mold the jug with a built in pipe coming out the bottom....What WERE they thinking?! Only other problem it had was caused by the stupid mounting of the 2- cylinder freon pump for the cold plate in the ice box. It was on a bracket welded to the baseplate, not the block. So, every time this big compressor kicks in, it jerks the belt and pulls the engine sideways against the poor mounting bushings, which were screwed when I got it. New engine mounts were OK, but I never like to have belts pulling against rubber mounts misaligning the engine with the shaft as it ages. Got room in there for the 4-108? It would never have fit in the Endeavour 35 behind the steps into the cockpit. Would have been fine if noone complained about the front cylinder and belt-driven stuff sticking into the galley, though...(c; The Amel Sharki's engine room is plenty large, but the hatch, the deck of the cockpit, doesn't extend forward enough to service the front of the engine where the fragile impeller and belts are located. You have to climb down into this neck-high trunk in the port lazerette, then bend in half to get through the little hatch into the port side of the engineroom. The hot water heater was in the way, so we moved it deep into the lazarette. I don't see how anyone tightened the belts where it was...which probably explains why they were all loose and cracked and burned when we got the boat home from Florida. The steps in the galley don't come off with a handy hatch dead right in front of the engine like the old boat. It's not one of the watertight bulkheads, of which the Amel has 3, so there was no reason not to make one there except you'd have to keep the down-sliding hatch up to use it. The emergency hand bilge pump is built into the step so it can be operated from the galley or cockpit, but I'd rather have the engine room hatch....go figure. Check that hose in the coolant recovery bottle....often. There's no indication it has no coolant in the heat exchanger until something bad happens...as it overheats. |
