Just repowered 222 fisherman it’s the 3rd best day

[Hineser Out]

3rd best day in boat owners life day he repowers. Had to repower my 2006 222 fisherman cause the f225 went belly up after I was running home from a 30 mile offshore solo trip. Luckily I was only 2 miles from home when the oil pump shaft seal broke and I tore up the engine due to no oil.

So I repowerd with a 4.2 Yamaha 250. I now own a Porsche. This boat is awesome with a 250 compared to old 3.3 225. So much fun to drive. Just past first 2 hrs so now I can open it up. It’s a completely different boat. At 3500 I’m doing 30 mph, 4500 I’m doing 37/38 mph, wide open I’m doing 44 or so. So much mid range torque it’s great.

One question is I’m wondering if I’m overpropped. Got a 15.5 x 17 and wot get to 5400, that’s slam down throttle and engine trimmed up to the max. All rpms match with the Yamaha perf bullitain for same motor same prop on a tournament except at wot. Maybe I should go down in pitch to get closer to 6000?

So how can I delete one of these post ? Cause it looks like I submitted it twice.

What hole is the motor mounted in? It's possible they mounted it too low.

It’s mounted on #2 hole which is correct. On Grady’s site I get same exact numbers as the performance bulletin for the seafarer with a 250 and it has the same prop, except top rpm. So I think next time I run
it wide open I’ll trim it up even more to see if it gets up over 5500. I really like the mid range performance the way it’s propped now so don’t want to change that if don’t have to.

Hineser,
I repowered in March and my motor got stolen and then repowered again when the insurance paid out. Both motors topped out at 5400 (1st) to 5600 (2nd) RPM. First motor I tested a powertech 4 blade prop 15.25 diameter x17 pitch and my original saltwater series prop 15.5 x17 . They stole the motor with the 4 blade prop. The 2nd one came with a SDSII prop identical to yours and it turns 5600 RPM. Top speed light load of my 228 was 46 mph.

I too have wondered about the performance numbers of 5800 to 6000 RPM on a 4.2 Liter F250. I have yet to see those kind of numbers on a motor now with 37 hours on it. I have been told as the motor breaks in it should listen up some.

So, did you go digital ? I did and love it.

Thanks for info Bob. Opened it up today for a little bit as it was choppy. Trimmed it up more and got to 5600 and about 46mph. I think there’s something to that , motor loosening up after break in. Really love this motor on this boat. It’s just so much better all around to drive compared to the old f225. I think it rides better as with higher cruise skimming over the waves. I feel like I can negotiate the seas better as well. My mechanic was impressed how solid the boat feels. I didn’t have a choice but to repower so at least it was a big upgrade in performance. I stayed with mechanical shift, save money and no need to cut up the dash. The square gauges I have are good for me.

Hineser,
I kept my gauges. I wanted that new big square full color LCD gauge but for the price I could upgrade my Garmin 4208 to new unit. I went for the digital throttle though. The motor is more torquey for sure. I like the sound of it too. I am going to try some other props in the spring to see if I can eek out a little more performance . Congrats on the motor again.

Just because it's mounted in the second hole doesn't always make it correct.That's the way it is mounted from the Factory,not always the best..I have a 2005 Seafarer ,F-225,Mercury Enertia 17" Prop. Hardtop and Enclosure.Have my Engine mounted as high as it will go....44mph @ 6k rpms.
