You may be able to go to a higher numbered pitch prop but check with a dealer/mech. first. A stainless steel prop may give you a little more speed also.

Go on a diet.

Top speed of that boat with a 90 on it is probably 38-40 mph. What are you getting now??

other than playing with props or lightening up the boat, your are farily limmitted to what you can do with out spending money for more power . you may gain a little here or there,but any great improvement will get exspensive. del

I have a very similar boat & motor, 90 HP Johnson on a 17.5' deep V Lowe, both 2002. The motor came with a 14X17 alum prop, and went 42 MPH according to GPS. Wide open throttle was exactly 5500 RPM. I wanted a more durable prop and found a rebuilt 13X19 SST (looks liked new to me) which pushes the boat at 45.6 mph, and dropped the RPM's to 5200 WOT.

I was a little concerned that the lower WOT may be damaging to the motor, I was reading conflicting things on the internet about such a reduction. In any case I went to my dealer and we looked up the specs on the motor and they said that the WOT range for this motor is 4500-5500 RPM, and "it is suggested that you operate the motor in the middle of this range at WOT" so I thnk I'm in good shape.

Just offered this info FYI since it is a very similar setup. I'm sure your Lund is heavier, but my boat is not a lightweight, fully decked, 3 batteries, 27 gal tank, tons of gear, etc., and I myself am no french poodle sizewise.

Find a dealer who will let you play with some of his props, and make sure you have it trimmed properly and see what happens... Good luck.

I wouldn't do it. Even if you buy a 115hp, your increase will be approx 5 to 8 mph. I wouldn't spend a fortune just to increase few more miles.

    • I won't be able to post the scores for this week until maybe Wed. so if someone else wishes to do so feel free to do it. In fact for the entire summer season I'm going to be pretty much hit and miss. So don't count on me the lake is calling and I have no computer there. My scores will drop like a rock unless luck prevails.
    • That should make things interesting

    • So I'm finally getting ready to get the boat wet for the first time this year.   I noticed last night the steering wheel is very tough to turn.  I did done research on some older threads on this site containing to my problem.   One tip I read was to check the big nut next to the motor on the steering arm.  Its printed on the nut -caution**tighten.  Some one said that nut should be loose.  Mine was wrenched tight apparently.  Does the warning on the nut mean , make sure its tight or do not wrench tight???  Btw it's a 05' mercury 115 if that makes any difference.   I will also re lube and clean the components also to see if it makes a difference.   Thanks for any input!!
    • Hey team, last miute success for the team...... nice tom too!!! Heading on vacation today will submit it mid next week when I get back. 22.11lbs with 10 3/4 beard. 
    • I will admit to this :   there are a couple of crystal clear, cold lakes in Yukon,  within a mile or so of my cabin, where you COULD actually eat and enjoy pike. They did not compare to some nice Grayling but  you COULD eat them. I'm not a fish eater unless it is fresh king salmon or kind crab but quite a few folks would eat the pike. And I will admit to enjoying a chunk of walleye now and then so long as it is slathered in hot sauce and I have had 13 double Makers Marks. But hey!.....you fellas enjoy them!
