Re: Transmission Maintenance Schedule

Tim, I agree with Cat Daddy... prop pitch is only one of several factors that influence performance and probably not the biggest one. We took 5 actions last winter to improve the performance of our 100 HP engines: 1) test injectors (we had to replace all 8); 2) adjust the valves properly; 3) find an...

Re: Mini Raw water stream?

Thanks John! Dick Tuschick also sent me this via email:

That is part of an anti siphon valve and should always be “peeing” when the engine is running over 2000 rpm it is critical that this vent never gets clogged as your engine could “drown” as it sits below the waterline.

Mini Raw water stream?

Can someone explain the purpose of the tiny port on the hull beside each engine that spouts a tiny stream of raw water when the engine starts up? It seems to run for a bit and then stops.

Thanks. Found a Seadog version at our local marine supply store. Installed it this afternoon.

Shower Pump Switch

The small rubber cover that protects the toggle switch lever for our shower pump has broken off. Has anyone come encountered this and come up with a simple way to repair the rubber cover. Or, have you found that the rubber cover is NOT needed? I suspect it IS needed and without it, the switch will f...

Re: Auto Pilot rudder re-calibration

I also had to replace the Raymarine rudder control unit attached to our starboard rudder. It simply stopped working one day -- we could not get it to re-calibrate. It was a simple replacement process and took a bit of testing to calibrate it. We also noticed that the location where it was screwed to...

Re: flybridge supply Breaker?

I am baffled by this... I have confirmed that the "Flybridge Supply" breaker does not supply power to anything... at least nothing that I can find. Everything on our flybridge (and elsewhere) works fine with this breaker OFF. Bit of a mystery...

Yanmar fuel economy

Can someone direct me to the fuel economy data collected for our 100 HP Yanmar engines by someone on this list several years ago? I seem to have lost the link.

Re: flybridge supply Breaker?

Thanks. I assumed it supplied power to the flybridge chart plotter, but I left it OFF yesterday while underway and the chart plotter worked perfectly. So far, I don't see any impact from turning it off. I'll have to trace it.

flybridge supply Breaker?

Does anyone know what the “flybridge supply” breaker on the 12v electrical panel is for? It does not control the 12v outlet or the 110v outlet on the flybridge.

Re: Engine burns excessive oil at high RPM's

I thought I had updated you guys on this issue. It is resolved. The excessive oil consumption was due to a compromised seal/gasket in the oil cooler. The cooler was reconditioned and, after reinstalled, the oil consumption on our port engine now essentially matches the starboard engine. For "Te...

Re: FORWARD FUEL TANK LEAKING

For what it's worth, I asked a friend who was a senior project engineer at an marine engineering company how he would calculate the size of the tank. He said: Since you can see the width and length of the tank inside the foredeck hatch, the height of the tank can be calculated by: H = (231.02 X 70ga...

Re: FORWARD FUEL TANK LEAKING

I agree with Bob's suggestion. Besides all the top fittings on the tank, the bottom floor likely slopes downward lie the fresh water tank... making it hard to mathematically calculate the size. Cutting the tank out and replacing it seems like the best long term solution. For example, our PDQ has a d...

Re: Need Window lock

I have a spare but I'm keeping it for replacing the latch when one breaks again. Given the design, they are quite vulnerable to breaking.

There was no minimum order when I placed my order at Pompanette.

Re: Managing heat in engine compartment

Very interesting suggestion, Dick. So both areas connect all the way to the fridge area? I’ve noticed the areas in front of and on the side of each engine and wondered if they had a purpose. Do you know if there is a way for fresh air to be drawn in from behind the fridge?
