On a tangent...I read that motorsailing can have stresses on the engine/trans/shaft mounting that aren't expected in the same way as just motoring.

When the boat is at rest, run lines across the interior of the cabin at a few spots in the general area of the engine. Then go sailing. When heeled over, are the lines still fairly tight? If not, the hull is flexing. What is happening to the motor mount, transmission & prop shaft during this hull flexing??? The more the flex the more you should be concerned with getting out of alignment during motorsailing, if heeling.

"How about Bull Dozer's"
Bulldozers are actually damned expensive equipment, with way more routine maintenance than you might think. You don't just use them and change the oil every six months.(G)
I'd bet the folks at Caterpillar would tell you they don't just drop in truck engines, either.

15 degrees

per Larry Berlin @ Mack Boring. Mine is a 3GMF. The oil sump on a bulldozer is probably like that of our Kenworth truck which holds several gallons, not a few quarts like a little marine diesel.

Something other than damage to the engine to consider if you are motorsailing while heeling over is getting air in the fuel system. If you have port and stb. fuel tanks and a crossover line between them (with the valve open) the fuel will flow to the downside and if your engine pick up is in the high side tank you can suck air in (voice of experience talking).

Re: Heeling while running diesel

Sorry for resurrecting a 7 year old thread, but I see real value in it and learned a lot today. My next diesel aux will have a dry sump and a intake next to the keel. Never can learn too much.

Dunno about oil.
Me too, thought we blew an impeller, finally figured out the overheating was due to an airlock picked up while we were motorsailing trying to beat some weather in (we didn't).

Re: Heeling while running diesel

Newt- I'm with you and appreciate the heads up causing me to read this.

What I wonder about is whether this is more of an issue with modern racer cruisers. Thinking ( perhaps untrue) is in pure ocean cruising designs with slacker bilges and more rocker the engine sat at or even below the waterline. A shaft could be employed. Now due to the shape of the canoe body a sail drive is required. Given where the axis of rotation of the boat is maybe there is more movement of the engine and it's fluids. Also wonder given limited bilges limiting placement of fuel tanks whether there is more risk of aeration and foam.

My westerbeke 55b manual says dont run at 30 degrees for more than 30 min. I think there is a separate 'installation' manual and it may only be mentioned there.

It'll depend on your motor. I'd ask the manufacturer, it won't take any more time than asking us bozos, and they'll actually have an answer.

edit: oops, old thread. Yeah, what 'hellosailor' said.

Re: Heeling while running diesel

My Kubota is a good little engine, but I think it was designed with tractors in mind. They have dry sumps in racing cars, aircraft and others- why not marine engines? Esp sailboat engines, which get tippy all the time.
In the meantime, I think I will limit my motor on tip to less than 30 degrees.
