Propped right on a 23DV?

[waterman7474]

01 DV with Ox66 250.  WOT is 54k at 43/44mph with maybe 40gal gas, 2 guys (400lbs) and a 50qt full of ice.  39-40k is around 27-28mph.  Hole shot actually seems to be pretty decent but the top end and cruising speed seem to be lacking.  Reverse is terrible.  This boat is obviously a little heavier than my 19 and it's an older motor so I'm not sure.  Only had it a month or so and maybe a dozen runs. 

Motor is running well.  I put in new plugs, new F/W separator, fuel pumps, vst cleaned out, oil set but.  I didn't do thermostats or the O2 yet as the housing looks very new compared to everything else so I think it was recently replaced.  The prop has one or two small dings and the edges could use a grind but it's far from bordertown bread knife status. 

There was something on it before and the PO got a smoking deal on this from a mechanic friend he knew so who knows what it came off of.  Before I got it, it was being used as a weekend charter boat to the jetties so I doubt if much went into "tuning" it before he put it on, especially considering all the other stuff that was rather carelessly rigged. 

Not looking to drop a ton of money on wringing every drop out of it but it just seems a little off.

As many members here have pointed me in the right direction, I will do the same. Contact Marcus at PowerTech or reach him here. His screen name is FunkyMonkey. Send him a message and he will get back with you eventually. He helped me prop my new engine and got it right on the money with the prop he suggested. You've already got the data he needs.

Thanks!  DM sent.

BTW, It does blow out pretty easily as well.

Mine was blowing out badly, also. Mostly due to the fact I was running a 3 blade on a tunnel hull (4 blade is a must).

Talked to Marcus at PowerTech.  SUPER helpful.

He did a little banging away on a calculator and suggested 3 blade, 15 1/4 x 17 or 18p, probably 17 as it is an older motor and maybe not as strong as it once was.

Such a great guy.

That may be a cheap replacement for a good prop..  Some do this when they sell a boat.  If you have access to try props.. The Yam SWS-II in 17 pitch would be a place to start.

A four blade prop will not be as fast as a 3 blade.. but will give you better bite and better push when loaded up with fish gear.

Marcus will dial you in..

Thanks.

He hooked me up with a local guy who actually knows the boat (and some of my friends actually) and agrees with what Marcus recommended, as well as the prop you recommended.  He has both as well as a few other options that he is more than happy to let me try out so that has worked out nicely.
