Data for Yamaha F150 on Aquasport 222

[305kingfisher1954]

Trying to decide on power for my 1987 22.2  Osprey rebuild ..Considering a Yamaha F150 Four Stroke..Just wondering if anyone has the set up that could share some actual data...How does she get on plane (I will be installing trim tabs) ...cruising speed at what RPM's, fuel economy...If you had it to do over again would you still go with the Yamaha F150 or go up in HP? ...Thanks!!!

SWS did a boat test this month on a Cobia 217 with a Yamaha F150.  They state the hull weight is 2,800 lbs which is probably close to the Osprey, give or take.  Here are their results with 2 adults and full fuel (90 gals):

RPM       MPH       GPH
4,000     26.5       6.6
4,500     31.4       8.5
5,000     36.0       11.2
5,500     39.7       14.3
5,800     41.7       17.5

You can also go to the Yamaha website and view test results that they did with various boat/motor combos, I'll see if I can dig up the link.

I think this is it:

Here's a little closer give or take.

70s and 80s (Hialeah built) hulls on the smaller Aquas were always lighter making them easier to gain performance from the lower hp motors. HP ratings were a little different in those days but a 150 will move this hull. It's just a matter of how fast you want it to move.

Interesting WOT fuel consumption @17.5 GPH, considerably higher than a two stroke or that engine is cranking out way more the 150 HP.

Yeah, I don't know about that, I'm not a numbers guy.  My buddy growing up had a 69 222 with a 112 Johnson on it and while I was younger and dumber at the time, that boat seemed to move right along. Interesting how much lighter the Osprey is compared to the Cobia, although I don't know the difference between "dry weight" and "hull weight", if there is a difference.

[Capt Matt]

My yamaha/mercury dealer always tries to sell me a F150 every time I repower with another opti. He tells me they are closer to 165-170hp than the 150 on the cowling. Still does not seem very good on fuel compared to a 2 stroke DFI

Thanks for the info and the Yamaha link. The Osprey 222 dry hull weight is supposed to be about 1800 lbs..I am rebuilding with structual foam...so I do not think it will be heavier , possibly even lighter..I found a Sea Hunt Triton closer in weight than the Cobia @ 2290 lbs, specs are'

RPM         MPH        GPH
3500        25.2         5.3
4000        29.5         6.7
4500        34.6         8.9
5000        38.5         11.2

The  recomended cruising on the four strokes are between 4000 and 4500 RPMS, if I could get around 32 mph @ 7 GPH, I'd be happy...
Thanks for your help !!!!!

have a 85 222-ccp just repowered w/250 yamaha 2stroke couldnt pass up the price $7000 STILL IN CRATE AND PLASTIC  I PERSONALLY WOULD NOT GO LESS THAN THAN A 200 HP HAD A 225 YAMAHA V6 EXCEL THAT WAS GETTING OLD BUT GOT UP ON PLANE NO PROBLEMS

[305kingfisher1954]

That was a great price on the Yamaha 250 Island..I'm still reserching the difference in performance for the Yamaha F150 and the F200.Trying to find a hull and similar weight like the Osprey on the Yamaha Performance charts...My aquasport is the 222 Osprey , much lighter than the CCP  ..dry weight is 1800lbs with a modified V hull with an 11 degree deadrise. This boat should require much less horspower to move her than your CCP...Seems like someone on this site should have a Yamaha F150 on this boat..Bayside Marine puts the Yamaha F150 on some of their restorations I've seen on their website..

The yamaha 4strokes seem to be dogs out of the hole. I'd say they have the least bottom end out of any brand four stroke made.  We've got one on our houseboat and have had lots of issues with it. Always seems like something is wrong with it, and it has low hours.  As a comparison our 19' carolina skiff sits right next to it on the lift with a 70hp tohatsu. The tohatsu can sit for months without being started, go to start it and it starts no problem every single time. Haven't had any issues with either of the tohatsu's we've owned. Wish they made some higher hp motor's. I would put one on my 222 in a second.

I'd check out the suzuki 4s in a 150 or 175hp. They are a perfect fit on the osprey hull.

[gran398]

That F250 is a dog out of the hole too.

The 175 Suzi or 175 Opti would be ideal on your ride IMHO.

Twelve degree Osprey requires less hp than a CCP.

Too much horsepower (classic open transom) on these hulls.... and they start acting weird. They'll roll over and plane off the port side (chine walk).

38 to 40 mph WOT on an Osprey is all you safely need.

You guys are right about the F series yamaha's, talk about sluggish hole shot and zero torque.  I ran a F250 on a 24ft bay boat during a fishing tournament. Heading in for the weigh in conditions had picked up a bit and I had a following sea with the tide running out at Gordons pass in Naples, It was nothing that I had not handled 100's of times in a much smaller 17ft flats boat even coming in through much bigger, rougher and faster moving passes like Boca Grande.   The motor simply did not enough balls to keep the boat up on top of the waves and surf her in.  She really badly wanted to get sideways and I thought several times we might be going over
Its not about HP its all about torque

Horsepower = Top End Speed                         Torque = Acceleration & Power              

You make the choice.

[damnitbadger]

Power to weight ratio you can't go wrong with the Opti especially on an Osprey.

[Necessary Evil]

I chose the Suzie DF175. It is a big block in line four with lots of Torque. Seemed a good fit for the hull. I got a verygood deal from Diamond Suzuki in New Smyna Beach, FL .

Hope I chose well! (remember the old knight in the Indiana Jones movie)!
