Author Topic:   Outrage 25, Yamaha F300

crow posted 04-04-2008 11:33 PM ET (US)
I have been considering purchasing a standard transom Outrage 25 and re-powering it with a Yamaha F250. I am also now considering Yamaha's new F300. I didn't realize they were currently available in the States. How do people think the F300 would perform on this boat? Its 804-lbs would be no heavier than the current twin Johnson 150's hanging off the transom. Would the hole shot, WOT, and handling of the F300 be far different to that of the F250? How would their [rate of fuel consumption] compare? Would [a Yamaha F300] look stange [because] of its size? Could [a Yamaha F300] even be trimmed all the way out of the water? I realize there are no real numbers to compare these setups. I'm assuming nobody has rigged a classic Outrage with an F300 yet. But I was just hoping for people's best guest and opinion.
I realize the Suzuki 300 is another great option (and 200-lbs lighter) but I really like my Yamaha mechanic and service. Thus I am curious about this new F300, the little brother of the F350.

I think it would perform fine. Probably would burn more gas at cruise than the F250 simply due to more moving parts.
I've seen the F350 in person and its enormous, probably standing close to seven feet tall. Visually it seems to me that it might look out of proportion to the Whaler which has a relatively low profile as compared to other boats. It's probably more motor than the 25 Outrage really needs.
If I were in your shoes, I'd probably opt for the F250, lighter, and it must be less expensive to maintain than the F300/F350. Also, its been around for a while so the mechanics are more familiar with it than the V8 4-stroke.

I think you will be happy with either Suzuki or Yamaha, however if your experience has been w/ Yamaha and you are comfortable with your mechanic/service shop, I would stick there, although many shops service more than 1 brand.
As for the 300 vs the 250, I think it would look a bit like you got a condo on the back. The 300 & 350 have a 6 bolt connection to the transom as opposed to 4 on smaller engines-you may want to research things like these. I'm partial to twins on larger whalers for a number of reasons (reliability, manuverability, general handling) but it would depend on your boating intensions (off shore or near land, etc.) Twins are a bit more expensive though.

F250 or Suzuki 250/300.

I think the size of the V8 Yamaha F300 and F350 motors is preposterously large for use on a classic Boston Whaler OUTRAGE 25. We have all become inured to very large motors, but the F300 and F350 take outboard motors to a new stratum of big.
Unless you really needed the extra 50-HP, the Yamaha F250 ought to be a good motor for this application.

The F-250 V6 has variable cam timing in the 25 long shaft version. The 225 does't have it yet unless it is in the 20 inch shaft version.
From what I have heard, the F250 is a great performer because of that. Considering the handicap factor of the added weight of the 300, I doubt there would be much of a performance difference between the two. The lower cost of the 250, less weight would make it my choice.

Yamaha has something of a price anomaly in their F225 and F250 pricing. The F250 is only about $500 more than the F225. Considering these motors are $18,000 motors, the extra $500 makes hardly any difference. You get ten percent more horsepower in the F250, and it is delivered with greater effect due to the variable valve timing. But the incremental cost is just a couple of percent more. I really don't see why anyone would want the F225 , unless they were limited by a capacity rating.

The F250 will also have drive-by wire very soon....

Sometime back we discussed that it appears your buying efficiency occurs at the higher horsepower figure. Using jimh numbers of $18k and $18.5k, the 225 cost is $80/hp versus $74/hp.

Be sure to check tilt clearance for a big new motor. The cowls on some of these high hp 4-strokes are just enormous, and may interfere with railings or stern seats.
