I'm looking for suggestions, knowing there can be no science or hard answers....

350 ci Carb'd engine
23' cuddy cabin boat
4100lbs

Current prop is a SS 14x19
Old prop (I'm assuming, becuase it was on teh boat) is alum 14x17

I don't know the WOT RPM as the outdrive is currently off; but want to get an
approximate or good starting prop for 1st sea trial.

I heard the current SS prop was hard to get up on a plane, had to be going
fairly fast, and once on plane, dropping off the throttle, it'd drop back off
plane.

Discussion, suggestion, etc is appreciated.

call your local prop shop mine here in Iowa has domo and loaners to try for
free if returned with no damage.

I'll check them out -- good idea.
Tacoma Prop here has (previously) taken back (exchange) props.

I live on an island tho, so "testing" tends to be a pain -- wanted a general
ball park idea to start with & then be able to adjust....

MerCruiser has a prop selector at
http://appcenter.mercurymarine.com/p... Gr5XDqQLvpAe_
that might be of interest.

I saw that -- doesn't go back to 92; and picking 2000 & going thru it; it tells
me:

Errors
Application outside of current selector limits. Please see your local Mercury
dealer or visit the Ask Mercury section of our website.

I have a 22.5 foot 2000 crownline 3600lbs 280hp with a EFI 350 cid
mercruiser and run a 19X14.5 prop.. w/19degree deadrise hull at the transum.

Planes fast and tops out at 56mph wot.

If you are looking for a better whole shot I would consider th 17 inch
pitch. Not really sure what you are looking for performance wise.(nore
whole shot or top end, Or the HP rating of your powert plant.

I have a comparable boat, slightly heavier, that runs
a 3 bladed 15 x 17.

Don't know if its optimal but it seems about right.

Great; thanks wayne.

can't do much without knowing WOT of current prop. But if it had a 17p
before I would go for a 14.5 x 17SS. The extra diameter should help getting
up and going due to having more blade area.
