Re: Pro/Con of outboard for blue water cruising
17" of travel is quite a lot; good find! I dunk my lower unit often as well. It doesn't seem to mind

Any idea how much weight/hp that Garhauer mount is built for? I am tempted to give them a call though mine is still fine...

Re: Pro/Con of outboard for blue water cruising
Hi DonCL,
I am not sure there max rating. You can get the mount with 1-4 springs depending on the weight of the engine. The mount seems well built with all stainless steel components. It is pricey, but I think it may be less than the most expensive garelicks.

Re: Pro/Con of outboard for blue water cruising
This has been a great thread and is very pertinent to the needs of alot of sailors. I don't have 10 grand for a new diesel in addition to the other projects I have on her and was ready to proceed with mounting a longshaft 20hp Merc of 90's vintage on the transom of my Bristol 40 yawl because the diesel is fried...and I want to focus on going engineless alot more than I have in the past anyway...I think even a boat of this size is a candidate for an outboard because she's rather "petite" for a 40 and I think an outboard well could be a good solution which could also solve the issues I have with the quite long,but narrow cockpit. I think I could lessen the tremendous cockpit volume of this boat by making an outboard well of sorts with a"lid" that could hold something light like life-jackets, revealing the well...but I may have to live with just a stern-hung O/b...which although it has the requisite down-sides of an o/b...at least I can hoist it off the stern with a block/tackle from the mizzen relatively easily when not in use..Just some thoughts...and again...a very interesting thread to many of us I think...
b.t.w.- if u are a sailor who likes to think "out-of-the-box" and havent visited this salty sailor blog : ChrisMorejohn@blogspot.com is a fountain of great ideas for many of us....and I highly recommend checking it out...

Re: Pro/Con of outboard for blue water cruising
I have a 6 tonne, 27' ferro and use a 6hp Mercury 2-stroke extra long shaft currently. It drinks about 2.3L per hour and averages 3kt. It's workable in protected environments like a bay or a river but for reasons already mentioned by others I'm looking to fit a diesel. It was pulled out by a previous owner but the driveshaft and prop are still there.
For the kind of sailing you intend to be doing I'd go diesel. Unfortunately they're not cheap, even in well-used condition.

Yeah Yanmar - Re: Pro/Con of outboard for blue water cruising

My boat came with an 25yr old, 3G Yanmar, 27 hp, and I love it. Had some issues at first with gunk in the fuel tank, but once we cleared that up, she has started and run without a hitch. Burns only about a litre per hour at 1500 rpms, a bit more at 2000 or so.
Lots of these around also, so it is not too hard to find parts or some old hand to who knows them well - an especially nice feature if, like me, you are somewhat mechanically challenged.

Re: Pro/Con of outboard for blue water cruising
A diesel is about 30 to 35% more fuel efficient than a four stroke outboard. A four stroke outboard is about 15 or 20% more efficient than a two stroke outboard at cruise speed. At idle the four stroke outboard is waaaaaaaay more efficient than the two stroke. Differences in prop efficiency can also make a difference.
My Capri 22 got 17 mpg with a 3.5 HP two stroke at 4.5 kts. It gets 20 mpg with a 4 HP Tohatsu four stroke at 4.5 kts. These are real measured numbers, not guesses.
The 4 HP will push it into strong wind and waves but the 3.5 HP would not. High thrust prop on the 4 HP makes a big difference.
Either outboard would push the boat to 5.5 kts. Hull speed is 6 kts.

My 8HP 4 stroke uses about 1 gallon every 4 hours pushing my 23 Oday along at 5kts.
Electric start
Quiet - keeps cabin quiet even when motoring
Alternator - charges battery
Fuel efficient - keep fuel, smells and noise out of cabin
Engine tiller makes docking a breeze
Worst case, an engine fire is OUTBOARD of the vessel

Sounds accurate
I have the 8HP 4 stroke Tohatsu on my 23 Oday. I came up with 4 hours per gallon at 5kts. This is just barely above idle and matches your 20 mile finding

Perhaps I'm biased but I find describing an Oday 23 as a 'blue water cruiser' ridiculous.
