Drop in boat speed when loaded?

Recommended Posts

I have a Crestliner 1850 Fishhawk and suzuki 150 motor. I can run 50 MPH with a lite load. When I add another guy and our gear I am down to about 43 MPH. It seems like a big drop to me. I was running a 23" Suzuki prop at about 5800 RPM's mounted one hole off of the transom. I have now raised the motor up one more hole and tried different props. Same result with about a 7 MPH drop in speed. I have heard of maybe lowering the motor to the bottom hole to increase loaded speed. Any ideas or is this a normal drop in speed?

Stainless or aluminum props?

What do your rpms do when you have another guy and gear in the boat, do they drop a lot?

General rule for props is the more blade area you have (more blades, or different style blades that are bigger) the better it will be at handling a load.

I drop 500 RPM's from a lite load to as compared to 2 guys with gear. These a ss props. I wonder if it is worth trying a four blade prop.

Have you tried a 21" prop? You're a bit short on RPM's when it's just you since you're running at 5800 RPM. That may help a bit and get you on plane a little quicker when loaded down, but you're not going to gain much in speed. I don't think lowering the motor another hole is going to help your loaded speed. It will likely make it worse.

I'm dealing with the same deal with my 1850 right now. I have a four blade on the way to try with the heavy loads. I'm going to have two props in the stow. A three 21 pitch for long range running when it is just two in the boat for tourneys or personal fishig and a four blade 19 pitch for guiding when I have four to five in the boat. It may be a pain to switch back and forth but with fuel prices every drop I save is a new crankbait.

I am curious how that 4 blade prop works for you. I have been thinking of trying the rev 4 by mercury. I hear that it carries a load well.

    • I just got back from a work trip to MI. I could not believe the difference in ground cover. We traveled all the way from Dearborn back to Bemidji heading through the U.P.  Most of MI had very little ground cover but WI was flush, green everywhere! I only got to check a few spots at rest areas but I never saw a thing. The ground was dry at most spots on the way home. I'm gonna go hit my spot tomorrow, hopefully it hasn't been picked yet!
    • love those when ya see them!!!
    • Took the kayak crappie fishing opening weekend and when calm always bring with the DSLR with. These turtles are glad the weather has finally consistently warmed up. I always find it funny seeing turtles stacked on top of each other and found a few along with multiple species which was nice.     
    • I was going to hunt wi this weekend but fishing musky with my fly rod is what I will do instead.  Good luck!!!!!!!
    • Anyone still at it?   not sure that i will get Isaac out anymore, will still ask these last few days.   Good luck everyone.
    • Haha, sounds like you have a good head on your shoulders and great perspective, Borch.  Plus, I think it's good to be upset about missing!  It motivates a guy to take more selective shots and make better shots.  My shot selection was ok, but my execution was not good.  I made a good shot at a stationary target, but the target was walking.  D-U-M, dumb!!!  Such is life!  Next year Morgan and I will shoot turkeys (as long as I can still get her out there).  
    • From what I read the idiot did not tell anybody....was asked to play in the World's and declined saying his wrists hurt so they made him go in and found the torn tendons...what a duffus.
    • It reminds me if the first year I took my son turkey hunting.  He had several close calls but didn't get a bird.  He was upset.  I said, "Why are you upset?  We got to hunt together for several days and had several exciting encounters.  If you shot one the first day we would have missed all that fun together"  He thought about it for a while and he smiled.  The older I get, the less its about the kill.  Reframing what I thought success was has added to my hunts.  Now, if I could get less upset when I miss a bird I'd have it all figured out.  
    • Excellent.  Nicely done.
