I am a spokesman for a major oil company in Houston. And I almost needed a lawyer when I bought my boat without telling my wife!

The 300s are great and much better than the original power 250s. But you will not get anywhere near those performance numbers in real water. We have bottom paint but even with new sprayed on paint we get .75mpg at 4000rpm with an average load. And only .65 at 4000 loaded for offshore dive trip...

I would like to know more when you figure out this issue as we have similar issue on our 360. Sometimes the indicator light for the stereo breaker does not light or flickers and sometimes it is steady on -- but the stereo works fine no matter what the breaker light does. The indicator lights...

FP changed the design of the relay a few years ago on its 8kw genie. Not sure what year but it was after 2006. There is a skinny relay and a fatter relay and they are not interchangeable. I suspect the skinny relays were overheating and opening the contactor which stops whatever function the...

Forgive me if I am being too didactic. Are you pushing the knobs in so they are flush with the drawer front? When you do that it pushes a deadbolt up into the cabinet and locks.

My electrician told me starter batteries are designed for high amp output for a few seconds (20-30) to get the motor started but are not a good option for house loads where amp hours are far more important. That is why you can't get stbd motor started sometimes, because the house load has eaten...

I suspect your vent line is partially or completely plugged and the tank is struggling to find make up air from another source like a leakly fitting during the pump out operation. Do not continue to do this until you clear the vent line because the vacuum can cause the tank to implode. Ever see...

Our GW360 with trip 300s typically gets 0.6 mpg at 5000 rpm and 35 knots with full fuel, water and six guys going diving. At 4500 rpm we get 0.7 and on a good day we might get 0.8 with a light load. A really good day is with the admiral off plane at 1.3 mpg. Went to Claypile rigs 75 miles out...

Look on the top of holding tank where you just might find a three inch diameter open hole where the tank saver valve is supposed to be. The valve protects the tank from imploding if you vacuum pump the tank when the vent is clogged. It and it's sealing gasket can blow out of the hole if the...

For comparison, on the GW360 the AC cooling water intake thru-hull has a scoop on it and the generator thru-hull is flush with the hull.

I routinely mix 87 and 91 (or 93) octane in our GW360 if there is no 89 pump on the dock. It actually saves time on the dock too by filling both tanks at the same time. You have to keep the starting volumes and stopping volumes straight in your head or on paper and it makes you stay focussed on...

We have decided to re-power our 2007 GW360 with triple Yami 300s instead of the original 250s. Is anybody running a 360 with the 300s spinning four bladed props vs the stock three bladed props? Since we have to buy new props anyway -- which also is the reason for the re-power. Looking for better...

I know two other guys with 2007 GW360 like mine and we all have triple F250s with three bladed wheels. My center motor runs about 150 rpm under the other two while cruising on manual throttles. I never use the synch function as the throttles seem to not respond properly sometimes when I take it...

If you are in saltwater check for hard growth on the metal parts where the engines move.
