Maxum 2300SCR 1991 Information and standard propeller size/pitch

[Maxum2300scr]

Hello All,
Thinking about the summer already even though it trying to snow here, Have not posted before because I wanted to get some use from my boat as it had a few problems after I purchased it. But after a remanufactured 5.7 mercruiser and transom housing I managed to finally get to enjoy it last year, including a couple of great nights in Plymouth sound at various anchorages.
I have been searching the net to see if anybody has any information on these boats, mine is a 1991 2300 scr with a 5.7 V8 4bbl mercruiser with I believe 1 :1.87 gearing on the outdrive and a 14 x 19 mercury lasaer II s/steel propeller.
The boat at WOT acheves approximately 38 mph which is great for a reletively big boat, but it does suffer with a very slow holeshot sometimes if into a wind it is actually hard to get on the plane.
Not that I want to go fast all the time I would just like to be able to cruise on the plane at approx 3000-3500 rpm and with the current set up it more like 3750-4000 rpm. I am wondering what propeller this boat should have as standard, as with the current set up it to revs to approx 4000 rpm as soon as I open the throttle fully and I get the impression it is just slipping in the water until the boat gets to a certain speed the the propeller seems to acheive good bite on the water. I have fitted the hole blanks for the propeller PVS system but I am sure it should have more grip at low speeds. Any information would be greatly appreciated.
