Avon SR 6 engine power, single?

[C-NUMB]

Found a project Avon SR 6, that considering buying. On the plate they it states
max 2 x 90hp engines, but how about single? How much Hp You need to get a reasonable speed, let's say min 30 knots? Guess You need a XL transom if running single?

Thanks for any input

Yep 25" for a single. I put a Honda 150 on one, went over 50 mph. I think a 150 would be perfect.

OK, thanks. Otherwise happy with the boat? I have a SR 5.4 wondering how much better the 6.0 is in the rough? Its much more heavier anyway.

I haven't been on a 5.4 (yet) but the SR6 rode very nice in the rough. Its a lot wider and you would enjoy the deck space.

Yes, the 5.4 is not a big boat considering internal space. For its size, seagoing is good, but guess a 6 would be softer, downside is it needs a bigger engine also. Some of my passengers think the 5.4 is a tad small.....

25" shaft 150 2 stroke yamaha right on the transom, no bracket. Handles great, top speed is around 45kts

Hi C-numb I just bought an SR6 and I'm also pondering about the engine size. Did you eventually bought the boat? And if so with what engine. My boat came from the Patrol vessel Kiila I from the coast guard and later naval forces of Finland. Not too many SR sixes in Finland i recon.

Hi

No,i did not. Did not have the time to check it out before the auction ended. Bidded ones but did not dare to go to the bitter end....I guess it was the same boat

Based on the comment from 95gstnj, sounds like 150 is enough, maybe even less would be fine?

Another thing, You need luck to get it registered to the bureaucrats at TRAFI...as its an old navy boat, even though its older than 1998/6 they might consider it has to be CE marked as You are the first bringing it to the "market". Stupid but this is how they think...I know some get away with it, hope it works for You too! Please keep us posted how the project proceeds.

Checked the online service at TraFi today. It's registered!. It even says on the registration that this boat would be CE certified
Maximum engine rating 180hp. Just as I put on the form. Could be bigger.. I read that the identically specced Zodiac(Avon) Searider 6.3 has maximum engine weight of 350kg. That would equal something quite big.

Now it's full steam ahead fixing some minor issues and repaint the whole thing (signal black). And of course gotta find me some engine. It seems that there are very few reasonably priced engines on the market right now here in Finland..

Great news! There is some plywood in those old Avon's, so might worth doing some test drilling before painting(deck, transom). The outside of the hull would sand down to original gel coat, it might be in OK condition, guess it painted due to its service mode(coast guard, naval forces).

If You have trouble finding an engine, sell me the hull...

Hi C-NUMB!
Well what do you know ended up replacing almost all the wood on the deck / stringers If you are interested check instagram with #avonsearider you'll see some build picturers. Planning to do a thread here also.

[C-NUMB]

Hi, nice work You have done, i bet you love the angle grinder cutting in GRP.... Yes, please do a build thread, would be interesting to follow!

Would it be a total overkill to put a Yamaha F225 on the transom? Weight is almost 280kg. Not a problem strength wise. But how about the balance of the boat?
