Auxilary engine size.

[ian parkes]

I intend buying a 4.5-5m rib in the future is there enough room on the transom of a boat this size for a small auxilary engine . and what size engine is required .

The reason I ask is that I have an almost new Honda 2.3 standard shaft that doesn't get any use now . I was just about to advertise it for sale, and thought maybe it could be a good spare when I get a bigget boat .

I did see a rib the other day with a auxilary engine stowed on the A frame , I guess they would have had a bracket on the transom to use it .

You should get a 2.3 on there-I can get a 4hp Johnrude on the transom of my sr4 alongside my 50 with external trim/tilt

BUT

I wouldn't expect it to be much use. Get a 4hp minimum. 2hp will just give you steerage way in moderate seas-4hp you'll at least make slow progress, even if it is across the tidal flow.

Last weekend I was pushing my 8.5 Scorpion at 5 knots with a 4 hp. enough to get you home.

The guy I bought my Destroyer from said that the 4hp he used to carry was fine in good conditions and would do about 5kt, but that you would not make much headway against a strong headwind or any sort of tidal flow. I guess from that it depends what conditions you intend to go out in - I am still torn between the better price and weight (easier to put on at sea) of a 4hp vs the increased ability of 5/6hp (but downsides of more £ & kg) if the main eggwhisk conked out in dodgy conditions. (The aux engine didn't come with the RIB as it wasn't his!)

Thanks for the help . I guess ill sell it and buy another when the time comes .

Standing around for a year won't help the engine anyway .
