Wondering what power to put in my boat????? Thinking Yanmar??

I bought a 27xcl Orca that had outboards on it. Not really into egg beaters and want economy. Diesel w/ duo prop is the only answer, but which one?

A pair of the 315HP yanmar motors in that baby would be SWEET!! Of course some B class cummins would work real nice as well and parts would be easy to get and you would be buying american.

If you have the cash--go with the diesels--I looked at repowering my 33 sportfisher with diesels in 94 with the Yanmars or Cummins--OUCH on the pocketbook!! I put in a pair of Gas pots and pulled out my broke down diesels--Cost the same in fuel--just ran less time on the boat from place to place--example--seattle to PA with diesels--3.5 to 4 hours(seas and wind dependent) and burned 100 to 110 gallons--same run with the 454's--2.5 hours and 100 to 110 gallons. So benefit is less time on the equipment and cost alot less to put in than the diesel.

Personally I would put a pair of E-tecs on her and go for it.

Have fun!!

Tight lines.

I don't think you can justify the repower and cost of the conversion from outboards to I/O on the basis of economy. The only justification I can see is if you don't have adequate range. Even then, it probably makes more sense just to sell the boat and buy one with a diesel in it. As far as Yanmars, some are great, some are good, and some are not so good. I have twin Yanmar 4LHAs (230 hp) which are great. The 6LPs (315hp) are great engines as well. If you can get a B series Cummins to fit, that would be a great choice. They are as bulletproof as you can get.

I'm curious as to whether or not a set of twin 300 suzukis would be decent on that hull.
I would think they would be an awesome set up and they can be found for a decent price new in this economy...
just my thoughts....they are fantastic motors

Live with the outboards or get another boat, the hull was not designed for inboards and todays outboard engines are reliable and economical to run.

I agree, the cost would be excessive unless you can do alot of the work yourself. I am running a Yanmar 4LHDTZ (190 hp) with a Bravo III, it burns between 3.5 to 4.5 gph the only weak link is the outdrive but Yanmar just released there own outdrive. You`ll need to sharpen your pencil on this one. Good luck

I agree with the suggestions to repower to a pair of good 4 strokes. I had a 225 Yamaha four stroke that was great. Very quiet, economical and easy to maintain. The cost of diesel parts are just frightening.

I understand your comment, and thank you for the input. Those boat were built for an I/O from day one. I was involved with the testing and research on the boat with several different engine options. I used to rig the boats when the owner had Skagit marine. I like the fact of doing 28 knots and only burning 8 gal per hour. The price I got the boat for I guess I can put what ever power I want. I have always wanted a diesel Orca of my own I guess?

thanks again for your imput , I listen to everybody

Cheers!!!

I can put a diesel in for less than 2 outboards...was quoted $20,500 for a cummins 300 hp w/ mercruiser dup prop. I thought wasn't a bad deal?

potfisher · May-21-2009, 11:54 AM

Fish Tech... I was shocked when I got a price on a 315 hp yanmar with the 350 yanmar outdrive...$25700. $5,000 cheaper than MER in Seattle. But Cummins NW came in at $20500 for a 300hp w/ mercruiser bravo 3(a little scared of the bravo 3) I think if Yanmar came out with thier own outdrive it must work?

Fishtech1 · May-21-2009, 12:13 PM

Corey, I have already had to replace the clutch in my outdrive and reseal it @ 400hrs. The B3 also has corrosion problems (I have purchased another back up unit), I did not want an IO but I did want a Yanmar diesel. When the time comes I would like to replace the outdrive with the Yanmar unit.

I think the Cummins would be a good choice also but the outdrive is still the weak link.

Any way you cut it if we are going to play we are going to pay!

Good 4 stoke OB is #1 option. I'm a Yamaha fan.

If a diesel pencils favorable into your plans, the STEYR marine diesels are worth considering.
