Hi all
I have a Norman 23 with a pretty reliable Mercury 15 4-stroke OB.
If I got stuck (again) in the reeds of the Broads I would love to be able to get to the next pubsafe mooring.
Want to store the auxiliary under the floor/bunks so really want electric.
What size motor would I need? Would a 55lb (1Hp) be enough?
Please assume little or no tide, and no great gale force winds.
I have 12volt batteries (one engine 85Ah and one leisure 110Ah) and a 50W solar panel, so no range issues - I only want it for back up in case of a failure.
All advice welcome!

Steve,
Did the reeds cause yr Merc to be inoperable ?
A leccy motor will push you along (1hp about the same as pulling it on a rope!) stopping will be poor!
Not sure on yr actual wishes - a 1hp leccy wont pull you out of the reeds if yr 15hp is tangled with weeds IMHO - better to clear it & pole out of trouble.

I think you are overestimating the power and range of an electric outboard. I had a 55lb on a canoe and got 3mph at full power. the battery lasted about an hour (keeping to a discharge of 12 v) you may only get 1 or 2 mph on a Norman 23. A small light petrol outboard will serve you better, my Honda 2.3 has no smell in the cabin if I run the carb dry after using it.

| Hi all we used 3.5 mercury as back up and stern thrusters on the Thames. Caliru has been exported to Poland. Our newer boat is a freeman 27. Regards Pete |

Adi, the Merc stopped(electrics) and we drifted into the reeds and spent 3 hours looking at a pub waiting for someone to come past (middle of December) .
1 mph would be fine if we ever got stranded again, we would just head which ever way the wind and tide was going.
Just have a concern over how far the electric motor would get us. There's a pub safe mooring every 30 minutes or so, that is all we would need to get to.
I really don't want to store a petrol OB under the floor, dry or not, and money is always an issue. New'ish 55lb electrics are about £150, which I'm happy to have in storage and maybe only need once in a blue moon.
If I left a 2 or 3 Hp petrol dry for two seasons rattling about with the water tanks, chains and tools, I reckon I stand a good chance of my back up not working when it was needed. Can't see me getting a good one for £150 either.
Any one want to have a stab at how long a 55lb would run at 1 knot on a N23? Let's assume slack water and a light breeze.
Thanks Steve |

What you need is a Seagull outboard. Leave it rattling around for years and it will start 2nd pull!!!

Don't store it under the floor, hang it on a auxiliary bracket on the transom - Seagulls as Dean says are pretty robust ! met a guy last weekend on a dingy with his wife, after 3 miles he had taken the small mariner off the back & put the seagull on due to probs (The seagull hadnt been run for 18 months !
