Hi I have recently purchased an old mirror and would like some advise as to what size outboard I can use when not sailing? I read somewhere; many years ago that a 2 or 2.5 HP could be used, don't remember where, but what about a lightweight 5 hp Mercury used at low revs?I would appreciate any ideas.
The mirror I recently purchased also came with a outboard - 4hp Johnson I was told that I should get some board approx 1-2cm thick to protect the transom
Interestingly the seller mentioned there was a technical measurement re outboard motors for mirrors that they should not exceed a certain size/weight/horsepower/whatever. I wasnt paying too close attention since it was not my intention to use the outboard.
You should be OK with anything up to 5 hp. A 2 stroke weighs less, so is infinitely preferable on a light boat like the Mirror. Also if you lay a 4 stroke down wrong, the oil can get out and mess the whole engine up...
2 hp may not be enough in tidal waters, and with a heavy load it will struggle anyway - 4hp is probably as much as you want / need, and will keep the weight down to 12-14 kilos. Make sure it's a short shaft - a long shaft will mess up the handling.
The transom of a Mirror is a very soft wood - you do need outboard pads - you can get ABS plastic outboard pads for about Â£7.00 a pair that you can screw to the boat. These weigh next to nothing, and aren't too unsightly.
Hi there - the long shaft will affect the handling by pushing the boat from lower down, and will tend to pull the bow down into the water. If you plane on the outboard it will be much harder with a long shaft.The extra leverage may also damage the transom, and if you are in shallow water you are more likely to run the prop aground!
