HP Rating with Lunds

This might be a silly question to some of you but I have owned many boats but not a lund Yet. I have noticed that the lunds require more HP then other boats in the same weight and size class. Just wondering why this is ?

I also noticed a huge range between the min and max HP rating. With the min HP bringing forth a nice mph at that.

So with that said I guess I have one more question………
Old school I was taught to go 2\3 between the min and max HP and you were good.
Now then a lund I am thinking about is rated 135 to 225 with 43mph min to 55mph max.
So with the old school way I would run 180 – 200 and call it good.

Now then dealers all across the usa are pushing 150 merc Verodos on this boat and claim it is the perfect engine.

Now folks have told me you need at least the 200 on this lund to be correct and just about every dealers is rigging with 150. What is the deal here ?

Thank You
Jim

Test drive the boat with the people and gear weight you would have 90% of the time. If the 150 does not perform up to advertised go to 200,225.

What model are you referring to? If it has jump seats and you are planning on using them I would certainly go bigger.

I didn’t know there was a minimum hp rating on boats. I was always taught, max out the hp and you were good. Dealers sell boat and motor packages at certain price points. The smaller hp motors work good enough for some of the boat buying public.

I think the minimum is what some manufacturers list as their “HP range”.

Brad thanks,
That is a good idea – how ever the sport angler is not one that many dealers stock.

Puddle Pounder Hi,
Tehy used to include min and max HP ratings as the normal some time back. lol
Min HP is what it takes to get it on plane and run safe
Max is as you said the biggest yoou can safely run.

I agree that dealers do at times ( alot ) mount certain Outboards to move them faster or they get a better return on them.

However it seems many lund dealers all throughout the usa are rigging with this newe 150 merc. verodo and claim it is the perfect engine for the boat. Maybe Mercury simply made toomany of them. lol

James,
There is no such thing currently as a 150hp Verado, the 150 they offer is a non-supercharged 4-stroke. Not sure what your motive is in making that statement repeatedly?

HRG

How the motor performs on a certain hull is only 1/2 the equation. The other 1/2 being resale value. You can’t hardly give a under-powered boat away. If you can’t afford a certain boat with nearly max power, step down (boat size) to what you can afford. You are better off with no boat then a boat you hate because it won’t perform.

HRG –
Why do you seem so upset over this ?
Here are a few examples for you.
Have a great week end

What was your point in linking to a 2009 thread?

Exactly.

James,
Yes, back in 2009, there was a 150 Verado, but it was dropped once the 3.0L non-supercharged 150 4-stroke was brought on line. You seem to be looking at new rigs, correct?

The Sport Angler is not a very popular hull in the upper-Midwest, most folks feel that the forward-console design provides a rough ride, as well as a small forward casting deck. But, as a troller, it should suit the purpose.

HRG

HRG,
They are still pushing the 150 V even today and that is all I know about that.

Now then None of this has anything to do with the OP and should not even be a factor in it.

Lets make this simple on my end and maybe you might understand what I was trying to ask.

Why do Lunds require Higher HP then other boats in the same size and weight class and even boats heavier then the lund ?

People keep telling me if the boat is max at 225 then you need to run 200 – 225 or it wont be good or under powered.

Lund list Min HP as well as Max HP. This means the min is the lowest needed to get the boat on plane and to handle well.

In this case 135 HP is Min
Max is of course 225
9 out of10 sport anglers are running 150.

A boat very similar in style and shape and is heavier runs a max of 175 and achieves the same speeds as the lund with the higher HP.

I know how the Sport angler runs. I know about what people claim and say about the ride. I simply want to know why Lund runs a higher hp range then other boats of the same ?

james

Not sure what you mean. Looking at Merc’s motor testing bulletins the same size Lund (even heavier many times) runs faster with the same motor than a Crestliner, for example. What are you basing your statements off of?

You say “A boat very similar in style and shape and is heavier runs a max of 175 and achieves the same speeds as the lund with the higher HP.”. Why not list something specific instead of speaking in generalities?

Compare the 1750 Fish Hawk to a 1775 Lund Impact with the same motor and the Impact is faster. These are damn near the same boat.

Top Speed (MPH@RPM)
39.0 @ 6000 for Crestliner

Top Speed (MPH@RPM)
44.4 @ 5680 for Lund

I ran a 1775 Pro V and would hit 43 with it with 3 guys in the boat with a 115 Merc 4/s and my buddy who ran a smaller Fish Hawk with the 115 4/s couldn’t even hit 40.

If you’re comparing to glass then say so.

One other possibility is that Lund doesn’t want a bunch of underpowered boats out there getting all sorts of negative press from unhappy buyers because their boat won’t plane out with a full load in it. Remember that if 1000 people buy a boat and of that 1000, 900 are happy with the boat because they chose to rig with a motor that has unough power to perform well. The other 100 went with the minimum rated motor that was a complete turd. Who do you think will be making the most posts? Will it be the unhappy customers or the happy customers. Unfortunately when people are happy they just use their boat and that is it. Very little positive feedback, but when someone is unhappy that is all you hear about. I would guess Lund wants the minimum rated motors to work well in most applications.
