It's to do with the oil in the water

You could buy say a 15 hp motor and change to a lower pitch prop, this would give you the acceleration to lift, the family on the plane, but would sacrifice a little bit of top speed. Would also help you power our of tight turns, as higher pitch props can cavitate badly when turning tightly.
By lifting the motor up the transmon slighlty can give you some of the lost speed back as the prop works more efficiently with the top blade in rotation just below the water sufrace in the created wake form behind the boat.

How about a strimmer with an outboard conversion kit?

We have Tohatsu 2strokes on the work boats at both my club waters. Good engines. Only thing that's ever gone wrong is the impeller packed up and engine overheated, and seized. Cost about £250 to put right.
Turns out the thing had never been serviced by the club! Got both done and they've been faultless since.

If there the jabsco type rubber impellors change them yearly regardless. For what they cost, not worth the risk as they harden

Quick update to the ally boat build thread.
It’s near enough finished now, or as finished as many of my projects get (useable but still some things to do).
I settled on a Tohatsu 25 two stroke outboard on controls and I have enclosed the bow and added a helm.
I wanted to not have to worry about running out of fuel or have extra cans loose in a small boat so I made use of the dead space where the pilot/passenger foot well is and fitted a 40 litre fuel tank which filled the gap nicely.
I then made a start on fitting the seats after modifications to the centre bench, basically cutting it down to about a third of its original height so I could get the seats in and have legroom under the faired in bow.

I added storage lockers to both the rear bench seat corners, fitted an isolator, a battery and a decent bulkhead mounted fuel filter with a glass sight bowl and drain tap for easy spotting and removal of any water in the fuel.
it was then onto fitting the helm (steering wheel to all you non boating types) and it quickly became apparent that in order for a comfy position of the wheel to be achieved and to accommodate the steering cable mechanism I’d need to raise the dash locally.
I did this buy letting in a bent tube hoop and then in-filling some nice sturdy 6mm plate to bolt the helm to. Then it was just a matter of rolling and fitting a closing plate to bridge the gap between the foredeck and the helm mounting hoop.

Lack of indoor space at work meant that in order for welding to be done I’d have to squeeze the front end of the boat into my crowded single garage.

Nice Jim
You leaving it all unpainted then?
Thanks Pete. No, I’ve got some more tweaks to do over the winter, like fit a screen I purchased a while back.
As you can see it’s going to need some extra metal here and there if that screen is ever going on, so I thought I’d do all the prettying up and painting after I’d used it a while to see if it needed anything else doing.

I’d love to leave it without a screen too but it really needs one. It’s quite a wet ride if it’s choppy and you are fighting a breeze off the port or starboard quarter. It picks up the spray and throws it right in your face. Also the itchen/solent is quite a busy and narrow stretch of water with some very large commercial and cruise shipping as well as regular high and low speed ferries churning it up so it gets a bit hairy negotiating their wakes. I’ve had a few waves break over the bow and with no screen to deflect them they end up in your lap.
Plus the boat goes 30mph, can get a bit chilly in the evening without something to hide behind.

And there goes the fact that any boat where you get wet is just too small. I understand the need for a screen of somesort. Though in rough water, hope its strong enough. When I was younger and dafter than I am now, used to mess about with power boats, a friend had a mishap with his drove the nose thought a wave taking the screen right off, boat was full to the gunwales, but with bouyancy tanks and foam in the floor it stayed afloat.
