Just a 'what if...?' this.
I was looking at the hull ID plate on my RIB (ex-Woody73 Humber Attaque 5.35) the other day for insurance purposes. The plate says it's rated for a max hp of 150. Given the fact that it's an early nineties boat (as far as I'm aware) does this mean that this rating is based on the assumption that we're talking about a 2-stroke. If so would a four stoke that weighted the same as an early nineties 2-stroke be ok as a replacement if it ever came to it? Something in the 90-115 sort of bracket?
Like I say, this is just a 'what if...'; I'm hoping
the 85AET doesn't explode first time I put it in the water!
