I know lots of people have done the upgrade thing. I bought my first SR4 / 25Hp from a guy who had bought it as his first rib. He bought a bigger engine, put the 25 into preservation, then after a couple of years moved the bigger engine to his "underpowered" ribcraft 5.something, and sold the SR4 rig with the old 25 on the back to me. 2 years later he replaced the 50 on the ribcraft with a 90 having sold a low hours 50....

Having done many cruises / rescue type things with the SR4 / 25 Hp, there is nothing wrong with it. If Mextli want's a SR, then that's the boat for him.
I wasn't looking for a humber when I upsized, but my curent chariot appeared at a price I liked, so I bought it. (I was on the lookout for an SR4.7). Would I change back now? Doubt it. Does it now have a bogger engine than I bought it with ? Yes.....

I now have more than double the HP I had on that SR, with a very small weight increase.
I still cruise at 22-ish Knots. I still drink about 0.8-ish L/mile.

There's nothing wrong with that combo.

You've not gone that way too

IMHO biggest engine you can get or you're going to always be wishing for a bit more like alot of things in life.

I had a SR4 with a 50hp and it was great fun I don't think it would be very exciting with a 25hp on, But if you're on a river with a 6 knot limit I've got a 6hp at the right price and I'd seal the flooding hull.

Triggers SR4 sold

I'll just see ... Someone offered me a 50 HP Merc Short Shaft for a very good price...

Could that be matched with the SR by cutting out the transom or is that a very bad idea?

just asking ...

But the sailing clubs towing dinghies & marks do so at low speed, in which case a 10hp motor would be ok.

Don't do it.

I think Whisper has a 3 cyl 40hp L/S Yam for sale, which would go very nicely on an SR4 - may be worth having a word.

I seem to remember from previous topics that a SR4 with a (lightweight) 40hp 2S came very close to the heavier 50hp 2S in performance (pick up is a prioroty rather that a few more kts on the top end) - can anyone confirm this and suggest which 40 is the one to aim for? I'm looking in the near future for the lightest weight SR4 rig I can find to beach launch (in suitable seas) 2 up.

And the fuel consumption at WOT per hour?
