Motor height set-up on a non pad boat?

[brownies]

Thought I'd knock the dust off of my 72 Ranger and play some. 72 Ranger bass boat, 16', Evinrude 70hp.<br />This is an old "cigar" style bass boat. No pad.<br />For prop/engine height set-up....do the same rules apply?<br />Or is it less critical on this type of boat.<br />Sort of looks to me like going over 50mph would almost be scary....

Lots of sliding i would think.is it an old tri-hull?D and kenny will be along to answer the question but i would think you would do it about the same.

I think it's best to get the AV plate level with bottom (the boat's, not yours) and start there to get a base-line started..seems like the third hole down is about all you can get with a good prop without adding setback...<br />What's that??..you need what?...a plate??? email me. I think I know where 5" of plate is...ktsander@st-tel.net

Ok Brown dude.<br /><br />Reminescent of my earlier days in posts I yaked on recently.<br /><br />Had 2 buddies with Skeeter Bass boats ('72 vintages, early in the days of he bass boat fever) and I had a thing that was a Falcon type boat.....was deep V like a tri hull in front, but a flattish bottom at the rear...do not remember the name of the boat.<br /><br />(Falcon is the brand name of a boat used to hunt for striped bass on the 89,000 acre lake Texoma (on the border of the states Texas and Okie). <br /><br />Big lake, lots of wind and fish are deep.<br /><br />They had 65's on theirs and I had an 85 on mine. Theirs was not deep vee on the frontal part and as it turned out, we both could run at 39 or a couple of miles under and that was it.<br /><br />Oh and their power was OMC and mine was Merc. Do not remember prop pitches, but all were SS.<br /><br />Now where the anti cav plate was positioned with respect to the bottom, or the transom dead rise, or the setback inches..... man, you were in prehistoric times then.....we knew nothing about that stuff.<br /><br />Mark

That's about where this boat runs best I can tell.<br />Yes, prehistoric times....and best I can remember, the speed was found by using speedometer...somebody elses....<br />(I know boat speedo's are not accurate, and, lets go one step further and say I was beside a guy that was looking at his boat speedo and it said he was going just over 35mph, and I was right there with him...lol).<br />This boat has NO gauges at all. I'll be adding a few though. Just for the fun of it I guess??<br /><br />Anyway, looks like a three V in front, rear is pretty much flat with what looks like a chine in the center.<br />Very rough ride in a chop.<br /><br />Going to add a jack plate to get the motor set-up a bit and start playing with some props.<br /><br />Wonder how this old dinasour will respond?

And this whole time i thought you was that tv star on bass tec my old glassmate is a trihull in the front and flatens out with a 85 on it long and narrow.it would only run 35mph.

2 answers<br /><br />brownies, <br /><br />The Ranger and Skeeter were pretty much the hull design in those days as I recall; very boxy design. Bottoms were flat (couple of ridges here and there (not lifting strakes) for the most part and no dead rise on the bow. Ran like a table top...flat and hard and too much hull in the water to get any speed.<br /><br />Then Forrest and his buddies got smart (as others did....I know Skeeter did too) and found out that a pad and vee frontal attack worked much better.....meanwhile the power industry is starting to crank out Vee power and the revolution was launched.<br /><br />----------<br /><br />Ron,<br /><br />Really the problem was the flat rear. I tried several SS props and even had "James Propeller Service" in Dallas tune up one especially for me and I could never break 40. Besides that with the deep Vee front and very narrow width, the thing was a bear trying to fish a point with the wind blowing.....made you seasick. <br /><br />Later,<br /><br />Mark
