Is my outboard to heavy

Sorry if this seems like a stupid question, but I'm new to all this, just wanted to make sure before I go too far. I have recently upgraded from a 20hp to a 40hp outboard with power tilt and trim which I have found to be a lot heavier as it would be, but was wondering if my 4 metre avan can take this extra weight, as I would sooner know now before I sell the old one? I have added a couple of pictures.

The boat should have a plate on it that tells you the max weight & HP.

Some older boats's didn't have the weight on the plate, so as a general rule if you get an engine of a similar vintage to the boat and it's at or below the Max HP, chances are you'll be OK, but no guarantees.

Other thng is if the boat is new, it will be designed to take a lardy 4- stroke. That looks like a 2- stroke Yammy? (which will be much lighter than what a new boat can handle)

What model is the engine?

the only thing i can find is a black patch on the rib tube with AVB18003F101 on it i guess this is maybe not anything at all .the rib its self would not be that new by the looks of it but it is still very clean and yes your right the Yammy is a 2 -stroke .

That serial number makes it a 2001 boat. That engine doesn't look too big IMO. Not like some of the stuff you see on ebay! Probably worth checking its within the limits of that hull that Avon state so as to ensure it's insured in the event of an accident. Is that a Supersport?

It looks like a Supersport to me.

It should be OK-but you need to seal those holes in the transom if they aren't already sealed!

Looks exactly the same as my supersport, I had a 40hp mariner/Yamaha on the back before I moved the engine to my searider.

It was fine with that on the back, in fact it flew!!! It did around 30 knots and was very stable in flat water but a bit skidy in turns and had a tendency yo leave the water quite easily

Plenty of freeboard on the transom though, more than the searider anyway...

Your rib looks very much like mine, guess that must be what it is, but I would never have known as there is nothing on it. I think I have filled all the holes in....well I hope so anyway as I have had to put on a new transom to raise the height as my old outboard was a short and this is a medium. I was just worried that the power tilt and trim had added to much weight, that and going up to a 40. I was thinking that I would have to give up my 6hp auxiliary as that may be asking to much with this outboard.

Supersports are a hoot.

I remember years ago having a go on one of the little ones with a tiller control 8Hp on the back and trying to see how far I could make it go sideways in a straight line before it actually started to turn!

Does it have a flooding hull? like the searider.

Looking at a boat with the same colour tube advertised as a searider (the stern photos shows the big hole)

I can't talk for earthdog's but my supersport doesn't have a flooding hull, and the hull is totally different shape, the supersport has a very shallow v and a raked bow, the searider deep v etc...

I didn't know what mine was either at first (actually thought it was a searider for a while) as the ce plate had fallen off, did a bit of digging on here and on the net and found out what it was. I then got back in touch with old owner, he found the plate in his shed and confirmed it

I am not sure if you will manage to fit an aux on the back, but maybe...

The supersport has larger diameter tubes than the searider, plus the sealed hull so I am sure it will support your outboard with no problem at all. Mine was a long shaft though?


The plate says 40hp max or 35 on tiller and up to 6 people (though not sure where you would put them!)

That sounds like fun! I know we had lots on this last year with the old outboard so I hope that's still the case. I can't think of any hole in the stern apart from small ones near the top where the steering was bolted on. I just found it a bit lacking in power when we were out with a bit of a swell and 3 of us on it, so I'm hoping I have a bit more power now when I need it.

As for the hull, the guy I bought it off said it had a flooding hull but not sure how to tell?

It's not got a flooding hull. There'd be a big hole in the stern if it did.

I bet he thought it was a Searider.

Now I know. I take it this makes it less stable when it's sitting still, although I have always found it to be fine even in rougher water as we quite often fish off it? Head spinning, even after all this, I still don't know what I have got?

Yes I do I had it out a lot in the winter mostly on ponds and in flood water but its the best thing ever. I have not been brave enough to put my small outboard on it and take it out on the river, well not yet anyway but it will go anywhere and its so much fun and for an 18 hp briggs its got plenty of power.

As its a fairly flat bottom it will sit "on the toobs" at rest. The flooding hull in the SR means it sinks a bit at rest and puts the toobs on the water to give it that stability, otherwise it would float on the "V" and be a bit more wobbly.

The only difference is if you stopped alongsde a SR in the wind, you would be blown sideways a faster then the SR, as there is next to nothing below your hull to get a decent grip of the water.

I would guess that's going to make naff all difference to you based on your planned useage.

Flooding hull

Yes i think your right, its not going to make any difference to me at all, but its so good to be finding out more and more about my rib, All i know is that when out on a bit of a choppy sea, its so much more stable than my old fibreglass tub .
