Dungeness!! My favorite crab. Looks like you had a power davit. That makes it really fun instead of a workout.
Yes, that one an E/Z Puller now have the Big Red Dog on the Marlin. We have the same motors, have 145 hrs
on mine they are fantastic.Doing more work than fishing, how is yours doing ?
I'm liking my Yammy fine. I just reproped it because the prop off the old 3.3 liter engine was too much for the higher gear ratio of the 4.2. I haven't got to splash it yet but I think maybe this Friday we will get a chance.

Boy, that's some might good eating. Those are just the right size for the eating part. By the way Mr.crab, I ran that 17 pitch prop today and it is an improvement. It definitely got me up out of the hole quicker/easier. The last trip I averaged 2.6 mpg and this trip it was 3.0. I did have a little less weight this time though. What disappointed me was that I didn't get the RPM increase I was hoping for. With the 19 pitch I could only turn 4800. With the 17 it would only turn 5000. I am still thinking that I am not getting a fully open throttle on the engine. I am going look into that next. At 5000 rpm the boat was doing 40 mph which gives 13 % slip which isn't bad. This boat should do high 40s with this 225.
My motors turn 5200 ,5300 with three bars 36 knots. If I bring them up to 6 bars turn 5500, 5600 41 knots
At 5500 is max hp. This is with normal load , close to full fuel as long as I hit over 5000 they shouldn’t be over
prop I think.
Yeah, I don't know what pitch props you have but they seem like they are in the ball park. I ran a prop slip calculation with your speed figures using 17 pitch and it came up 2.88% so evidently they aren't 17 pitch.
I had my wife with me and she hates to go fast so I was only able to run up to full throttle for a few seconds before she threatened with the fish knocker so there was no time to play with my trim. I have my trim gauge calibrated so 3 bars puts the anti-ventilation plate parallel with the keel and that is where I had it when I found 5K rpm to be WOT. No doubt if I trimmed on up a bit more to fine tune it, the rpms would have been a little higher. If the sea state is calm enough to run fast I normally trim up in increments till I sense a little porpoising and then trim back down till that stops. I didn't have the time yesterday. It was too rough outside and too busy on the inside. The snowbirds are still clogging things up a bit here, although it is less than a month or so ago.

Went fishing yesterday, sturgeon 54 1/2 “ 87 lbs still not sure of my prop size. Thinking motors should hit
5700 to 6000 rpm, but did release the fish.
