Welll, actually, there is a little more to it, as you probably suspect. Here's the deal. (I've also made this post on another local DE forum too, I know some of you read them both).<br /><br />I just installed a 1996 50 HP (4-stroke) Mariner on my Lowe 1760 MT fishing boat (basically an aluminum open hull), and the Mariner came from a much heavier boat. Which means, it hits 6000 + RPMs in less than 3 seconds. I tried it yesterday at Massey's, and I was literally on plane before I left the dock (I know, no wake area, but trust me, it made no wake, only the prop was in the water). Had to stay above the dredging pipes too, and fight the wind, yada yada. <br /><br />Problem is, I don't know how big of a prop I can go to, and I'm too cheap to buy a couple of different ones to find out. Dealers tell me I need a 14 pitch, but I think the boat will handle more. (I have a 12 pitch on it now). <br /><br />So, just to be sure, I want to find someone that has a 15 pitch prop or a 16 pitch prop to try on my boat. My catalogs tell me that just about any Mercury/Mariner/Suzuki/Force motor in the 30 - 70 HP range will work (the diameter is approx. 3 1/4" (gearcase) and it is has 13 splines). <br /><br />I live in the Smyrna, DE area, and will travel about an hour any direction to give it a try in the local waters near where you live. I'll bring you a grab bag of saltwater lures too, for helping me out, or take you fishing in the boat once I get it set up with my new prop. <br /><br />If anyone can help me, either post back here how to get up with you, or e-mail me your phone number at seadawg007@hotmail.com and I'll call you on my nickel. <br /><br />Or, if anyone knows any prop shops between Smyrna and Indian River Inlet that allows "try before you truly buy", I'll give them a shot. <br /><br />I may not get a chance to check my e-mails or back on this forum today, but I'll look on Monday for sure. <br /><br />Thanks in advance.
