Congrats, dw 8928. As Larry said, that looks like a lot of boat in 31 feet. More photos and stories will be welcome. Whereabouts in Florida do you aim to move her?

Very nice package, DW! I've long been impressed with the Camano Troll/Helmsman 31. As others have said, it's sure a lot of boat for its size.

Please keep us posted on your delivery trek and first impressions. Congrats of the Best of Year Christmas present!!

And what do you mean by "auto oil change"?

"Auto oil change" as in it bleeds off a little dirty oil while replacing it with clean oil?
Here's a write-up on the Seasall engine if interested. The engine in mine is essentially just a re-chipped version of this engine:

By all accounts, the Camano Troll was overpowered at 200 HP. I have to wonder why Helmsman went with increased horsepower?

Very common now. My boat is overpowered at 380hp in my opinion.

Wifey B: Ours is underpowered at 2400 hp in my opinion. I was really wanting a Nor-tech Roadster or something but now just lusting after an AB. Not real fast but they will mostly run over 50 knots.

Helmsman has a pretty big analysis of the engine and the power curve, prop pitch, fuel burn, etc. Might still need to be throttled back though at 240hp, but at least it has some reserve power!

You will likely be running the engine way under loaded unless you run 12 knots. And that's going to use a lot of fuel.

Not everyone wants to go 8 knots. If you have a planing boat...that planes....you can never have enough power. Those Camano/Helmsmans have pretty nifty hulls that move thru the water easily.

Precisely, and in any case, I think this paranoia about running larger engines underloaded for periods is somewhat overplayed, as long as they have a good old full power burst from time to time.

And you can never have a too large fuel budget.

My full-power surge achieves hull speed.

If your quest is speed, consider something like this:

Not somewhat, greatly. All the engine manufacturers advise you how to prevent that from being a problem. Typically it's bring up the load for 30 minutes every six hours or something similar.

My understanding is that the newer diesels don't have the same problems with running under loaded like in days gone by.

Yeah, I wanted to say that, but thought it might bring a sh*t storm down on my head from all the 'experts'...

We chose a higher hp version of the engine in our boat...480 vs 380 hp.
The decision was made for a number of reasons:
First obviously was that the boat will have a higher top speed when and if we want it.
Second, after a couple of deliveries totaling some 120 plus miles, I became aware of a harmonic in the 380 hp engined boat. When I described this to the factory, they told me that I was describing the harmonic associated with a 4 blade propeller in an aperture. The fix? A 5 blade propeller although less efficient will alleviate the issue. The 5 blade prop is a good fit with the larger hp engine...
The final reason was that the 480 hp engine get a different transmission and ratio. The lower gearing of 3:1 vs 2.6:1 allows the higher rpm engine and different propeller to work optimally in the range of speeds our boat will operate in.

Finally, we are told that in spite of the lower gearing and 5 blade propeller, the higher power drivetrain gets better fuel mileage than the lower power drivetrain at a given speed.
In other words, we will consume less fuel unless we push to the highest speeds.

We have a number of sea trial spreadsheets of the various combinations that back up the claims so we are hopefull...
