does anyone have an lund tyee 1750 grandsport with a 115 2 stroke, I want to know what my top speed could be ????what type of prop are you using also?

Your GS is heavier than my 17' Fisherman. I run a 150 and run 50 or so no problem. A guess would be low to mid 40's?

i would still like to hear from someone with the same boat!!!

Use a prop calculator to calculate theoretical speed and the speed you could achieve at xx% slip. You should be able to get in the 10-15% slip range with it dialed in right. That will give you the best idea.​

Not too many Lund owners on here. There may not be anyone here with the same boat/engine.​

Already gave you my opinion on the prop forum. You might also have a waterlogged foam problem if the previous owner left it out uncovered in the rain alot or it sat tied up to a dock. My 16 foot Lund pike had over 200# of water logged foam under the floor when I replaced the plywood/carpet this winter!!!

My Sylvan 17 ft Pro Fish is probably fairly similar. Makes 52 with 115 Evenrude 2 stroke.

Sounds like an indash speedo or pedal wheel fishfinder speed to me. Really high performance bass boats take some work to get those speeds with a 115. A rivited hull aluminum boat is never going reach 52mph on GPS with a 115 unless you pull the whole interior out and run around with a close to bare hull, Even a welded hull aluminum wouldn't reach those speeds due to the design limitations of aluminum. My boat for example has had 3 different pedal wheels and one pilot tube indash speedo in it since it was new, All 4 read quite a bit higher than GPS speed with the pilot tube being the worst. With a 130 yamaha on the back (boat rated for a 75) it showed 58mph on the dash, and 55mph on the fishfinder. Actual speed was 52mph gps. With a 70hp 4 stroke I see 45mph on the dash, 42 on the fishfinder and 38mph GPS speed. The dash and fishfinder speedos are now removed from my boat and I have new fishfinder with built in GPS for speed.

Not too far off the chart, my 17' Angler SS speedo is dead on with my GPS. 30.4 mph with a Susuki 115 4-stroke, all of the 32 gal of fuel, and 2 people. But I'm so way under propped (13.5 x 15)! Hope to have that rectified within a month or two.

Re: how fast with a 115 2 stroke?

i was looking at where my motor is mounted and its at the lowest setting is that right or should it be up?

Re: how fast with a 115 2 stroke?

As Mike (Esox) stated, I don't think there are that many Lund owners around here. Best case may be to get a response for something close in weight. Unfortunately I'm not overly familiar with all the different Lund models and what they weight but only believe my 17' Angler SS is a heavy boat.

I saw you have a post up in the Prop Forum. That is likely your best bet for answers with this issue. I tried here with prop questions at one time hoping to hear from another with a very similar setup but pretty much struck out as you are now.

After reading for a while, I'm getting the impression you want the motor as high on the transom as you can get to reduce the uneccessary drag from the lower unit. But I have no actual experience with this specific topic to assist any further than what I've gleened from the Prop Forum information of just keeping the ventilation plate at the water line when running and just low enough to prevent excessive ventilation problems.

Re: how fast with a 115 2 stroke?

Go to Lund's website and get their 1-800#. Call and ask for Engineering. They have test data on tons of boat and motor combinations. They can give you a much better idea on what your boat could be running.

Re: how fast with a 115 2 stroke?

Not sure what motor mfr you have Marty but that's an idea. I called Lund but they said they have no info/suggestion for a Johnson motor on the Angler SS. Well... no other suggestion than get some different props and try them, which is the same stated on this site.

Re: how fast with a 115 2 stroke?

Most of the major engine manufacters have test data on their websites also. I don't know how old your boat is but most of the 115's on 17's are about 40-43 mph.

Re: how fast with a 115 2 stroke?

ok now is an after market prop going to be better(faster!)than an omc 14 x 17

Re: how fast with a 115 2 stroke?

It will if you go with a stainless steel prop.

 

[Tcrum5711]

Re: how fast with a 115 2 stroke?

The sky is the limit with the after market props. Most likely only a couple will work well your particular rig. It took 2 props and raising the motor a hole at a time to get the best performance out of mine. A lot of time and testing different setups went into that.

Re: how fast with a 115 2 stroke?

where are these holes you are talking about are they for the trim(on the motor) or on the back of the boat itself?
