Marine generator question (cost?)
I'm in the final stages of buying a boat, and the generator is not working.
The seller has agreed to fix the generator as part of the sale, or replace
it (up to a maximum, yet-to-be-determined price) if it's not repairable.It currently has a Kohler 5kw gas generator. What would be the replacement cost if: a) I got the same unit as a replacement or b) I replaced it with a diesel generator (and had to add a small diesel fuel
tank) |

| ===== Sticking with the same fuel (gas) will be more convenient and less
cost up front. I installed a Kohler 7.5 KW gas generator in my old
boat and I belive the cost with installation was about 8 or $9K. Last
year I installed a 20KW Kohler diesel with a sound shield in the GB49
and the total cost was around $19K of which installation was about $6K
and the sound shield (highly recommended) about 1K. Diesel gensets
tend to cost about 20 to 30% more than gas, but are cheaper to run and
possibly more reliable. Speaking to DSKs point, I would seriously reconsider the decision to
buy a boat with gas engines unless it is under 10,000 lbs or so. Even
then I would still consider diesels knowing that you use your boat a
lot, and that you might be interested in longer range. Operating
costs are about 50% less with diesel, range about 100% greater and
resale value considerably higher, especially with a heavier boat. |

| Grady White 300 Marlin with twin Yamaha 250hp outboards. I have limited draft clearance at low tide. All of the diesel boats that I
like draw too much water. Plus, they're too slow. This Grady is a 45+ mph boat. So what's a replacement genera |

| Nice boat, but at 45 mph, that "hawg" must burn close to a gallon per
mile per hour, somewhere between 40 and 50 gph. Yikes! What's the optimal cruise, 30 04 35 mph? |

| So I'm I'm not that far off in figuring about $5 to 7k for a replacement 5KW |

| Better than I expected for 2-strokes.
Optimum cruise: 32.6mph 1.43mpg http://www.yamaha-motor.com/assets/products/otb/bulletins/bulletin_otb_2StrokePerf_OX666_250hp_0190-GRW-Z.pdf That same boat with 250hp 4-strokes:

| == I understand, we have the same issues here in Cape Coral. There are
some diesel I/Os being produced but I have no experience with them. |

| Why are you buying a boat that's big enough to have a 5KW genset, and
it's not diesel? DSK |
