Ive tried looking online and asked at boat shows and the whole nine but i still come up empty handed. I have a old volvo 280 outdrive but the boat is under-propped big time! Everyone has suggested a 16x23 LH but still havent come across nothing. Can anyone recommend someone to me or know of anyone that might have one laying around ?

thank you

There might be somebody out there that makes a prop insert that will allow you to run Merc props.

What engine package do you have?
The Solas Titan props are great for old Volvos.
I run them on my Magnum with 280's

I have a sbf 351W that's pushing about 375 hp

What pitch would I look for if I run the merc prop

What kind of boat do you have? Do you know the ratio and at what rpm would you like to spin the motor? Target speed?

I have a '78 P&D. When i ran it this weekend I got 44mph at 5000rpm. Not happy at all especially when the motor is pushing 375hp. I want the most speed I can get. I was also thinking of applying a nose cone so I can get mph wherever I can

At that speed, the nosecone will slow you down.

Are you looking to go up or down in rpm? At what rpm is the motor making 375 hp?
