What outboard size for SEAGO 270 airdeck?

[davethedog]

As title really, currently have a 2.5hp yamaha 4 stroke outboard and find that it is not that quick with the SEAGO 270 we have. So, possibly looking at getting a bigger outboard, say 5hp? Thoughts?

It will tell you in the handbook - 6hp. Will get it on the plane at the cost of much greater weight and fuel, but if you can handle the weight on and off the boat and you want to go longer distances at speed or carry heavy payloads then quite reasonable thing to do.

I have a 260 seagoing wooden slatted floor that planes at about 12-13 knots with my 3.5 two stroke with my 14 stones in it, add another person and it won't. I've had the engine on my mates 270 air deck and it's the same.

The maximum recommended outboard power for a Seago 270 is 6hp. but 6hp outboards are a good deal heavier than your 2.5 Maybe a 4 hp will be adequate for your needs. Borrow one from a friend to try if possible.

Check the weight of any that interest you before you buy.

If you are keen and fly...modern dinghy like this are rated for 4 stroke outboards and their associated weight on the transom...you might be tempted to fire on a 6/8hp Merc or Yamaha 2 stroke ?
So much more grunt than the modern single cylinder and heavy 4 stroke.
That said...if you are looking for any type of performance from your tender...you will need a better one than that. Get one with an inflatable keel at least. They plane and track much better. Without, the slatted floor type dinghy tends to gulp air under the hull and make the engine cavitate and skitter at plane speeds. Not a nice thing.

Agreed: I have used the same 3.3 two-stroke on three inflatable dinghies: first a 2.7 airdeck - planed nicely one-up if you get your weight in the right place (holding tiller at arms length), no planing two-up or sitting aft. Then a lighter 2.6 slatted floor - depending on which floorboard(s) your weight was on would plane cleanly or not - ie worse than the heavier 2.7 airdeck.

Then a bigger and heavier still 2.9 with airdeck and inflatable keel - planes beautifully one-up almost wherever you put your weight, and although not properly planing, faster than either of the two smaller dinghies two-up.
