I suppose I should post my thoughts on the Aqua Marine
MyTGen as ours has been installed for four years now and we've cruised almost 22,000 miles with it. Overall, I've been happy with it but it's not without issues.
First, is the overall design. The engine
pumps for both the coolant
and raw water
. The water
pump failed after only 200 hours but the replacement pump has been fine after almost another 1,000 hours. I wish I had gone with a belt-driven rubber-impeller raw water pump
was time-consuming. The engine
did not come with a wiring
harness (the instructions that came with the engine recommended hiring a marine
electrician to do the job) nor did it come with motor
mounts. There was an error in the wiring
diagram. I had ordered my genset with the optional high coolant
pressure shut down but no diodes were sent with the engine although, a phone
call to Dan, the owner of Aqua Marine, resolved that issue quickly.
The engine is very noisy and there's no sound shield available. Even though Rutea's engine room is very well insulated, the genset makes more noise
than our Beta Marine
90 running at cruising speed.
On the other hand, we do get a full 150 amps of current
out of the alternator
and the engine only uses .39 of a gallon of fuel
running at full throttle, full load. The engine has not used any oil
nor does it leak. It always starts easily (I don't even use the glow plug). The oil sump only holds one liter of oil and there is no oil filter
. I change the oil every 100 hours. Dan, the owner, has been pretty good about responding to my emails although when the genset recently blew an oil seal
(made a monumental mess all over my once-clean engine room), he recommended that I stop in at the local Kubota dealer. At the time, we were in a remote
part of Borneo.
I guess the bottom line question is: Would I buy the MyTGen again? I think I probably would. It's small and light and the price/value ratio is very high but there have been some compelling posts here on CF about people building their own and having good success with them. Frankly, when I was searching to buy a genset, I found very few choices in the DC-only arena.
Fair winds and calm seas.
