I just picked up this boat from a forum member.  It is an old 34 Luhrs that came originally with twin 318 inboards.  Both engines are removed.  Ultimately I would replace them but in the mean time the previous owner included an outboard bracket.  He mentioned installing this and putting on a 150hp outboard.  Seemed like a reasonable temporary fix but I am looking for any feedback.  I realize this would be for displacement speeds only.  Thanks for any ideas/help!

34' and a 150

Just wondering, would that get you much more then trolling speed?

I had a 1968 Plymouth Barracuda with a 318ci and a two barrel carb. If I remember the HP output was 230HP  X2...460HP

5,000# 25' Century Cuddy w/350 260HP....25mph

First, even if you put steering on the motor, there is no way in hell you would be able to control it. Parking would be a bitch with no wind and impossible with anything above 4MPH! Second, you would really need to have the right prop for it and even then, I don't think you would get much more than 10 knots at WOT.

No, displacement speeds.  I had a 26' and could get to hull speed with a 9.9 kicker motor.  Pretty easy to get to 8-9 knots.  That would likely be about it I would think.  150 wouldn't be necessary, could get away with alot less I think but he mentioned 150 so I quoted him.  Not sure how this boat would react though with that much weight hanging off the back and two engines removed.  Might be a wash?

This is not a permanent solution, just temporary to be able to move the boat around

If it was just to move it from one marina to another and only once, it should work (with a few friends expecting you at the new marina to help you). One motor of the back of a 34' will not gave you any control in tight areas (like the dock). Not to mention, it's gonna kill you in gas...

How far and how many times are you contemplating moving it. Would it be worth the trouble of hooking everything up vrs towing it? Wouldn't take much more then a jon boat.

I have run lots of boats and agree on the maneuvering.    Fuel should be easy though, as peak efficiency is at hull speed.  This should make for good conversation.  I would guess fuel would be somewhere around 4nmpg at 7 knots. A big outboard should be running low RPM's at hull speed.

Temporary meaning less than a year.  Would it be worth it?  I am not sure, if it is just mounting an outboard than probably.  Wouldn't be cruising extensively but would like to be able to move around without towing.  Boat is a project so taking care of everything else and then investing in a couple new engines.

I would think that by the time you buy an outboard, the controls, the hydrolic steering and hoses, the key switch and harness, pay to have the transom reinforced for the weight, seal where the original shafts were so they do not cause a water leak and sink the boat, etc., you could probably find some decent engines to go in. Just seams like a lot of extra cost and headache for a band-aid. Just tryin to help.

Once the boat is together, I think you will enjoy it. Looks like it will turn out good.

I couldn't agree more.

If you need it moved tow it.

What is your long term goal with it?

That transom is not designed to withstand the weight of large outboard - mount a lighter, smaller, tiller handle kicker if you need something simple to just move the boat around a marina or short distances.

Thanks for all the replies.  My long term goal would be to just fix it up and  use it.  The boat seems to be solid, just needs(substantial) cosmetics.  My plan would be to start working on it and keep an eye out for a pair of 318's or 360's.  New long blocks with heads are cheap enough but then there are all the bolt ons that are needed.  I was looking for a way to be able to move the boat under it's own power(even at 6knots).  I may just mount a kicker bracket.  Hopefully it is light enough without engines and fuel that it would be okay with a 9.9 or so?

Please explain why you need to move it?

Is it to get it away from that dock, go play with it or what?

I put a bracket on a 25 Mako for a fellow in the past. he hung a 9.9Hp motor as a kicker on it.

He was less than satisfied and removed it.


Don't get me wrong here, but your posts on this, it seems you are hell bent to spend money and time to get some power on this boat.

Any power and thus doing it your pissing up a rope.

Two reasons really, first I need to get it away from the dock it is at and move it.  Secondly is I really don't like the idea of not being able to move under it's own power.  I don't really care if it is 5 knots as I wouldn't be heading offshore or anything.  I am thinking the easiest thing would be to just put a kicker bracket and find something under 20hp for the time being.  Hopefully that will work.  The boat is pretty light with no engines, no fuel and most of the inside stripped.  Is this a feasable idea?

I realize this is not an ideal situation.  Anybody know of a pair of 318's out there?

enough of giving him a hard time because it's not the way you would do it guys............yes Joe, it will work, as X said it won't be anything close to ideal or even very usable but it will work.  You will waste some money doing it but it will do what your describing .......as mentioned earlier, avoid any kind of wind or seas

Thanks Scott-  I am okay with wasting a few dollars on a kicker bracket.  I am looking for engines and can find long blocks but I don't have any of the bolt ons.  I have a few calls in to try and find a complete 318 or 360.  Appreciate the help!

i might be able to round up a set of cummins 210hp engines to drop in it. i'll have to rebuild one of them first though.

Now you're talkin!  Price would have to be right as the boat is not a beauty queen and I am trying to not go nuts with my spending.  These did come out of the factory with twin Perkins diesels.  A pair of 210 Cummins would be sweet!

i converted my sportfish from gas to diesel back in 2001. best move i ever made. i put in a pair of 250 hp cummins. a few years ago i rebuilt a pair of 270 hp cummins that had sunk at the beach. i bored them .020 over and turned up the pumps. they are close to 300 hp now. love the cummins!! easy to work on and the parts are not too expensive compared to other brands of diesels.

And at the end of the day, all were satisfied! I wish I could be around for some of the Alaskan Halibut, I bet it won't be from a store. I hear that's some good eating fish. Hope you have lots of fun on the new addition!
