Tioman…..repairs

The trip to Tioman was great. Caught a few fish.

Ate more fish for a while than I liked 😄

Got some nice diving in and certified some folks. But just when all was well trouble struck. Pulling in to the marina …. nothing no forward no reverse. A very nice local in his little dinghy towed us into a slip. YAG! The engine works…hmmm…. well is there something wrapped on the prop … nope. Not good. Look inside it’s clear the shaft doesn’t turn in forward or reverse. Time to dig in.

Check the pressure in the transmission should be 120 PSI, nope it’s zero. Maybe just out of fluid. Nope fluid is full and clean. Somethings not right between the engine and the shaft. Time to pull the gearbox.

This spacer must come out. Turns out it’s really hard to do.

Those bolts come from a vibration dampener that are oriented so the prop shaft has to go out about 4 inches. What happens when it goes to far? Oh you have a large hole in the boat and it sinks. 😳😳😳😳 investigate …. I have a PSS dripless shaft box. Awesome can’t push that very far. Oh wait I need 4 inches…. put a rope on it and pull. The gods are laughing moves about 1/2 inch. Well I remember from Physics pulleys help. Try one better, rig another….

7 pulleys later and 3 days of working on it. Success!

That cursed spacer is out, but wait that wasn’t what I needed to check. The gearbox has to come out.

Did I mention it’s heavy? Like 30 kilograms. Take a look at the gearbox, perfect. In fact it’s unbelievably smooth. Turns out it’s designed for a 500 HP engine not my puny 80. So what’s wrong? Dig deeper time for the tranny to go….

Oh look the damper plate that connects the engine to the tranny is stripped. Time to get a new one.
