Re powering my Monaro 24 with a 300 hp outboard. What 300 to use

About 2 k lbs more than the 28 foot 8.6 kf I've been on.. and almost identical fuel economy. Best I can get is around 2knots per gal. 350 verado.

Impressive
 
That’s really good fuel economy you’re getting, nice rig. I’m a mechanical binnacle guy, so the 250 Suzuki or the 300 merc sea pro are my pics. Buddy runs a fleet of sea pros out of Zeballos and has nothing but good reviews. The 300 has proven itself and is available with mechanical or fly by wire.
Haven’t priced a new motor out, scared to with the tariffs.
Good luck with your hunt!
 
Also check on warrnty lengths, to me thats a game changer
 
Merc has a 7 year promo to July 10th...i bet it is extended tho.
thats awesome , unfortunatlly here in vic area unless you wanna haul boat up island no dealer down here
 
My KF 28 twin Yam 150s fully loaded fuel water 300 pounds of fish 4 people. 1.8 mpg at 30 mph. My buddy same boat with 200s is the same. My other buddy same boat Seapro 400 1.5 mpg.
Those are real no BS numbers
 
I run at 4100 to 4300 doing 26 to 29 mph depending on water conditions best is when its about a 1 foot chop
Pretty incredible you’re running the same speed as me, turning your engine 400-600 rpm faster, on a boat that weights a few thousand pounds more than mine and only burning a half a litre more fuel. Would love to see the live data on that with a photo.
 
Well apparently it’s not when dual prop 350 zukes hung on a bigger and heavier boat are matching my economy 🤔
Some boats are harder to push, I know Grady’s are not that fuel efficient , hull design, deadrise and a lot of factors involved, props, gear ratio and I can go on( dual prop) single prop, Suzuki have a reputation to be good on fuel, see on mine I just put gas in it and send it lol
 
Price it out, but a 300hp Suzuki was over $10k less then a Yamaha at the time. Warrantee and Tourque are also considerations. I've been on the Suzuki for a couple of years, and just love the motor.
