Need advice - SR 5.4 + Yamaha 115HP 4 stroke?

I found 5 years old Yamaha 115 HP 4 stroke and I do not know if this engine could go to my Avon Searider 5.4?
Is it not to heavy?
Really need your advice guys.....
Thank you

that is going to be too heavy i'd say.

most seem to go with 90hp yam 2 strokes as the ideal setup.

cheers

No chance. Best bet is to let me buy the 115hp and I may have a Yam 90hp 2 stroke here at the moment which could be available at the right money

The transom might handle the weight id you beef up the support bars. ,make something up out of scaff poles and plate but it would porpoise a lot providing the stern didn't didn't forget to float. A Yam 115 2 stroke however is a lovely solution.

How heavy is the four stroke I'm thinking 195 kilos which is a lot of weight tats even more than me!

The Suzi 90 (new model) is a light 4 stroke and that comes in at 148 kg but thats still a bit lardy

But apparently " Hull rateings are flexable and open to change."

The 115 4-stroke would be a bit heavy...I run a 115 2-stroke on my 5.3 Zodiac and it does very well. Like others have said the 2-stroke 90 will get the job done. The Zuki 4-strokes in that class are impressive too.

Back in '91, I bought a new Fletcher 140 that was rated to 85hp on the manufacturer's plate, while the handbook, sales brochures and all other 140s I've seen from that era were rated to 75hp.

And No, I hadnt' tinkered with the plate.

Too heavy, even if transom takes it, it will sit too low in the water. Water would come over the transom if a duck swam past! As for reversing, best have a bilge pump ready or some plastic scoops.
