Fuel use ?bigger is better
Just a quick one chaps
I have a caribe 13 with a 30hp 2stroke mariner from the 90s. The rib is plated up to a 40hp (doesn't state max transom weight however).
It goes ok with the thirty, but takes a bit of leaning forwards to get over the hump with three big lads on board in any real chop.
I was wondering about putting a 40hp 4stroke on the back at the end of the season. Would my fuel use go up (more horses to feed), stay the same, or go down (frugal 4 stroke?).
If the plate doesn't state a max ob weight is it ok just to stick to the hp limit?
