petter

[warwicksail]

Hi did they every make a 10hp single cylinder petterdiesel engine if so does anyone know much about them? I have seen the minni ^ before but unsure if it will have enough grunt for my 21' westerly sailboat

10 HP should be plenty for your boat. The single cylinder engines tend to run a bit rough...since they're thumpers... The more cylinders the smoother an engine generally runs...

This concerns when you say noisey how noisey? wot kind of speed do you think il get with 10 hp my only concern this will be there for emergency and in esturys with regular 7 knot plus tide you may understand

[sailingdog]

Generally, sailboats shouldn't depend on their auxiliary engines in an emergency... the engines are far more likely to fail than a properly used rig is...

Hull speed on a 21' sailboat is about 6 knots, probably a bit less since the waterline is shorter than 21'. A 10 HP engine, properly propped, would get you close to hull speed, if not up to hull speed... so if the tidal currents are 7 knots... you'll be wanting to plan your trips accordingly.

I was going to say...a 21 footer fighting seven knots of tidal current WILL lose, irrespective of the engine.

Owning a sailboat is generally more about cooperation with natural forces, not trying to overcome them.

Yup... I agree completely.

I have a friend who has a hardy diesel tractor. I don't think he put a dime into it in 15 years outside of oil and filters. Yes it is ugly and most likely heavy as hell but I bet it runs and runs.

Wow, when & where were these things built? Or is that a prototype engine for the new Russian spy boats
