    How should I power this hull?

    Ok guys, Help me choose. I have two outboards and two of the geared set ups. I would really like an EP-1 outboard for this hull but it's not in the budget. I am leaning away from the Roqua outboards because the videos Ihave seen of these in use leads me to believe I wont get up on plane. I won't go brushless as I am not looking for ultimate speed and Idon't like burning batteries.

    What are your plan's in building? Fishing boat, Race boat, or something to just cruise around with.

    RE: How should I power this hull?

    Cruise around but lift the bow enough to be able to cut through some chop.  I might style it as a work boat similar to the pictures below.
     
    This police boat is about how I would like the hull to run. It does not have to be up on the pad like a high performance boat. 

    Maybe with a cabin similar to the red hulled Whaler.

    RE: How should I power this hull?

    Go with the salem Harbor master.
    One time I was looking for Dia-cast police cars and found a site that they have all kinds of parts like lightbars that work with LED's. Don't ask me where that site is now.[&:] But I'm sure with a little digging you could find one.

    Speed 500, direct drive, possibly the larger red prop.

    Wayne the seller seems to be a good guy. Answered in detail the questions I had for him (while the hull was in transit) and sent me pictures to reference from another build. He even sent me this:

    RE: How should I power this hull?

    Bob you feel direct drive is the way to go on this one? I can change the motor itself and prop to whatever if need be.  I was planning on running two standard size stick batteries.  Hmm, I think you might be right.

    That drive set up came out of one of these. 29" by 9" Before the ABS plastic hull disintegrated.  I always felt the prop was way to small


    The two geared drives are from this which is roughly 36" by 7" but not a planing hull

    RE: How should I power this hull?

    The direct drive and larger porp is more likely to give you the planing you desire. If it is too much, switch to the smaller prop. You can also control planing with throttle.

    The plastic boat the motor,drive shaft came out of was designed to go at a somewhat scale speed, thus the small prop.

    That second boat is a Police boat. When push comes to shove the real one could get up and go.

    Hang on to the geared motors. You may come on to plans for a tug one day and use them both for a nice powerful tug boat.


    One more thing. That hull reminds me of a PT boat.

    RE: How should I power this hull?

    I got the hull from Tollytime over on rcgroups. He had one posted on ebay a while back and I contacted him a couple of weeks ago to see if I could purchase one. He is known for his PT hulls.

    RE: How should I power this hull?

    These were two ideas the seller showed me. I like the one with the standoff bracket but I would mount it closer to the hull with a well in the middle of the transom for the top of the motor instead of trimming the sides as shown. LOLNot that I have an EP-1. Might have to rearange the rc garage and get one. If not then the direct drive set up seems to be the one I'll use.

    RE: How should I power this hull?

    Yep, that's why it looked like a PT boat hull.  I purchased a PT hull from him over a year ago but haven't had time to work on it.  It is a beautiful hull so I will have to build it - someday.   You're right, he is a great person and I think a very good craftsman.

    RE: How should I power this hull?

    Since the boat can't go forward faster than the water being shoved backward by the prop, the prop needs to be smaller for more speed, and spin faster and/or have enough pitch.  Counter intuitive until you consider Newton's law about every action having an equal and opposite reaction.

    RE: How should I power this hull?

    I have to agree with "mfr02" on that point.  At least you have the two props tio work with so start with the smaller one.  Another point to consider is CoG, if the Center of Gravity isn't right the boat will not get up on plane either.  See my comment to Wayne on his Lobster boat build.

    RE: How should I power this hull?

    Ok, now what about the prop angle relative to the bottom of the hull?  What about rudder size?

    RE: How should I power this hull?

    Here's some information for you to check out:  http://www.glen-l.com/designs/specia...lx1-notes.html

    At first I thought about 10 degrees but then I thought I'd better research the answer.  Here it says "approximately" 12 degrees.

    RE: How should I power this hull?

    Here's something else I found which would indicate that a lesser angle is better. Might be why speed boats have zero degrees relative to the bottoms of the boat. http://www.castlemarine.co.uk/download/propwalk.pdf

    You may also want to consider using a double rudder for better ontrol.

    RE: How should I power this hull?

    Nope, my Mother in law has been in NY for a few weeks.  Since she is the only baby sitter we have for my one year old and my wife is gone from 8am-7pm most business days I am pooped by the time she gets home.  Meaning both the work boat and this project have been on hold.  I It's killing me to walk past he hull in the garage all day.  I think I am going to work on the decking and cabin before I worry about the drive system as I would hate to put holes in the bottom of the hull since I really want that EP-1 outboard.   Time will tell. 

    Hey how did you end up mounting the camera on the deck of the lobster boat?
