weight or hp whats more important?

[nick mc]

say you had a rib that was rated to take an engine of 150hp but also rated to 340kg, would you be happy putting a larger engine on it as long as it was within the weight rating?

anyone that can give any advice it would be much appreciated.

cheers

I would be happy, my insurers may not be

My thoughts are pretty much the same as Dry Run's In normal use if the extra power was used within the boats capabilities then it should be fine
The problem would arise when there is a problem IE when you need to make an insurance claim it's possible the insurers would use it as a reason to reject the claim
Even the engine being slightly overweight wouldn't bother me unduly as it's no different to putting a fuel tank in the stern or hanging an auxiliary on the transom
You could try asking the manufacturers if they think it's OK and if they say yes getting it in writing and going to your insurers and asking if they will still provide cover or just ask the insurers but I can guess the answer

Cheers kinda what I thought just need to find a suitable engine now 😂

Do i personally think it is a big deal to overpower a boat by a few HP? Not at all. But as the guys above stated, insurance is your primary concern. Here in the U.S, they will search for any possible way to void your claim before they pay out. This goes for all Cars/Boats/ATVs/Accidents etc. If you got a Nice/New/$50k+ RIB, you should play it safe IMO.

Just my Cent.
