I am repowering my outrage 25 which currently has twin 1985 200 Yamahas. My dealer tells me that I can repower with 4 stroke 200's but I am concerned about the added weight. The new motors would weigh 583 pounds each. What are the implications and how much weight can my boat handle?

I also have a 25'Outrage and was considering on repowering. My outrage has the whalerdrive. (Rated at 450hp) I decided to keep my current setup a few more years while they improve the technology and reduce the weight of the current 4-strokes.

I don't think the older whalers are truly designed for such heavy outboards,(583 pounds each!)The implications, can possibly be a transom failure. I saw a picture of a 22' with twin 4-strokes and it looks unbalanced with all that weight in the stern...Remember, the dealer will make alot of money on the sale, not to mention future service work from selling to you...He will tell you anything to make a sale...

If those Yamahas are still running, I suggest you stick with them till they blow....Just a suggestion, Good Luck! Homey.

Thanks, I have Whaler Drive as well, and the hull is an '88. I actually called Whaler today and they told me that it shouldn't be a problem even with the added weight.
My old Yamahas are over 300lbs lighter in aggregate, but they are shot so there in no choice about making them last a few more years... I've been doing that for the last few.
Thanks very much for the insight, though.

A few months ago, I had the opportunity to sea trial a 25' Guardian with twin 225 Mercury four-stroke engines mounted directly on the transom. The boat did squat a bit at rest, but the quiet and smooth power of those engines made the boat a pleasure to drive. I am not sure how the additional weight (over two stroke engines of similar HP) would affect the trim on a recreational model with the Whaler Drive. The Guardian planed briskly and ran very well in rough water with those engines. It had the 30" transom upgrade with a full-height splashwell bulkhead.

The maximum engine weight for the 25' Guardian is 970 lbs. I assume that rating would increase somewhat on the Whaler Drive version.

At the time the 25 WD was designed, 1987, with the 450HP rating, the heaviest engine that was available at the time was the OMC 225, which weighed about 460 lb. So we know it can handle 920 lb or so.

As an example Mercury 225 EFI's now weigh 477 lb, which should also not be a problem, and your fastest option. Mercury 225 Optimax's weigh 503 lb, probably a stretch, but OK. The 225 4-strokes (any brand) would really be pushing it in my opinion, and give you inferior performance to the above two anyway.

I would not get the heavy 4-strokes in the 200HP rating, but rather opt for the smaller and lighter 200HP EFI (OX66) or HPDI engines.

By the time you find out it's too heavy, it will be a costly mistake. I'd recommend OPTI, FICHT, or HPDI, technology, or smaller 4 strokes.

Please, take it from an outboard mechanic, you don't want any Opti or HPDI. Briefly, Evinrude has the best patent on their injection system, therefore the best technology, ergo the best outboard. The proof you can find out by yourself, look under the hood of a ficht, then look at all the extra parts/things that are included on Opti and Hpdi. Merc EFI is good, just not very fuel efficient. Yamaha carburated is wonderful, but burns even more fuel and parts cost alot more than any other outboard manufacturer.
