These do have a neutral gear, well the 3.5hp does anyway. F/N but no reverse

Many thanks for all the replies, and especially Les for offering me the use of your outboard which is very good of you. I would worry about damaging it to be honest and I have today bought a Mariner 4hp which seemed like a good price?

I can't wait to get out with it and give it a go I just hope it stops raining

Mariner 4hp will be fine, a fair bit heavier than the 3.5hp at 26kg but it does have reverse gear.

Well the sun was shining this afternoon so I took the old girl out for its first trip along the Thames at Reading.
I have to say, it didn't feel right for some reason.
I wasn't expecting to go very fast, but every time I opened the throttle more than about half way the motor felt like it was pulling itself under the boat and pulling the boat with it. It probably didn't help that I was sat at the back and I'm about 90kg, plus the weight of the motor, and there was no- one else to help weigh it down at the front. It also felt more difficult/stiff to steer, the more the motor was pulled under the water.
I ended up sitting on the side tube as far along the boat as possible, but not even half way along as i couldnt reach the tiller, and that helped a bit but I felt like I was going diagonally all the time.
I suppose I could extend the tiller handle so I am sat more central, and I guess it would help when the boat is fully loaded with wife and kids, but It definitely didn't feel right.
When I did open it up, the front end lifted, the back end dipped but there wasn't much in the way of speed increase.
Can anyone throw any light on why, or am I to expect this from the set up I have, which is a thirty plus year old Avon Redseal with no solid floor, and a similar aged 4hp Mariner.
Any help would be greatly appreciated

Sounds like the motor is pushing well but not getting much resistance from your tubes, sounds like you need more pressure to me,were the tubes good and hard throughout? although as you have suggested I don't think you will be breaking too many speed limits with a flexifloor..

Thanks for the reply. I did wonder whether they should have been inflated more as they weren't as hard after a couple of hours as they were when I set off. I presumed they had lost a little bit of air but didn't know if it would make much difference as the boat didnt feel right o begin with. Next time I will inflate them as hard as poss and see if it makes a difference.

Better to have a rigid floor and some weight at the front,is your floor inflatable? and is the outboard short shaft and a 2 stroke? because a long shaft will be no good and a 4 stroke dam heavy,if your floor is not an air deck,then it needs slat's.

It's a 2 stroke, the floor is just Hypalon material, not inflatable, although I used the previous owners three small slats made from grp, although they are quite thin material and didn't seem to be doing anything. I am going to make a floor from plywood, probably in three pieces to cover the entire floor, and will see if that makes it any better.
