Won't plane

[Troubled boater]

Hello everyone trying to get some insight on my problem I have a brand new bass tracker 175tf with a 60hp mercury 4 stroke with gear full tank of gas it will get on plane but is very very slow but once it gets to plane it will run great and get to wot trimmed which is 5900 to 6000 rpm now the real problem is if you add a nother person and a live well full of water it won't plane at all it just bogs at 4000 rpm unless one person shifts his weight to the very front till it gets on plane then it's fine I know it's a weight thing but can changing the prop solve this problem the max hp for this boat is a 75hp so I would think a 60hp would not be that much under powered the prop that is on the boat come on it brand new as a factory package sorry for the long post just a troubled boater with concern of the poor hole shot performance any help would be appreciated.

What prop pitch do you have? 3 blade or 4 blade? I know what you mean, I've got a very similar weight (995#) boat that I got with a 60hp too. Should have gotten a 75. But mine (lowe stinger 175) is 65" wide at back and haven't had a problem getting on plane with it with 2 big guys and gear. But I don't use the live wells. Assume you have it trimmed all the way down for a hole shot. Mine came with a 12P spitfire 4 blade, but quickly replaced it with a 14P ss 3 blade prop. Might try going down in pitch and going to 4 blade if you now have a 3 blade. or just going to the same pitch in a 4 blade to replace a 3. If you can get the dealer to replace the 60 with a 75, that would be what I would do. My dealer wouldn't. I'll never buy anything from them again.

Thanks for the reply I'm not sure what the pitch is but it's a 3 blade aluminum prop I to would say to drop the pitch but once I'm on plane and the motor is trimmed I'm right at the wot spec's .now my question if I understand props from what I have read if I go down in pitch it will help my hole shot but over rev on the wot end help please I love the boat and the way it handles once on plane but if I can't get it on plane what good is it I'm very concerned if the boat is that under powered why would they even sell that setup

Remove the prop and look on the ends for size

This is what is recommended from merc prop selector. I used 600# people and gear to include 120# for a 10 gal live well. This should be pretty close at to what pitch you need. [h=3]Your setup[/h]

Ok guys I have some more info for y'all the prop that is on the boat is a 10x38x14 with 13 splines and the gearing on the foot is 12x22 1:83:1 loaded heavy will not plane at all bogs at 4000 rpms and stays there if one of us moves to the bow it will finally slowly plane then you can get to wot trimming the motor and rpms are 5900 rpms hope y'all can help all info is muchly appropriated thanks again

 

[Troubled boater]

Oh and it is a 3 blade prop thanks again

 

[alldodge]

I'm going to guess the 10x38x14 is a 10 3/4x14, so go down to a 10 1/2 x 13 pitch 3 blade
See if you can borrow one

If going for a less pitch prop, motor will overrev badly when lightly loaded along increasing fuel comsumption due to revving much higher.If the max wot rpm range is 6 K, it's the max the motor will rev with current pop.

To plane faster your actual 60 HP motor is a must shift weight up front to balance the combo correctly, once on plane let your buddy move backwards while maintaining sufficient throttle so not to go off plane. Check if the motor sits at the sweet transom height, that's with no water splashes side or back transom nor with over revving issues, if control box opens fully the carb's butterflies if being a carb model.

Thanks I have noticed even on blaney the stern corners are close to the water and it does spray on the sides of the back but not much does this mean it is to low in the water never had this issue with a boat before

It's normal to have small water splashes at stern corners, front "lower leg" as seen from behind, should produce no water or side splashes when at full throttle, for that must visually check what's going on at back motor as this scenario will slow down the combo a bit. If with mentioned splashes rise the motor one hole up..

Ok checked the cavitation plate with straight edge on the pad and the cavitation plate straight with the pad the cavitation plate is a 1/4 " to 1/2 " above pad and the motor is in the last hole as far as you can go down on the transom so I'm assuming from what you said the cavitation height is spot on please correct me if I'm wrong just trying to rule out any wrong set up

 

[WesNewell]

You've got a 22.25" transom so it's mounted at right height. I'd try a 13P 4 blade and see if that won't get you on plane loaded with livewell full. If not, a 12P 4 blade certainly will. That's what came on my boat. It's sitting no being used now.

 

[Troubled boater]

Ok thanks but won't that over rev rpms at wot if I'm already close to that at wot now I'm just trying to understand sorry if y'all are getting frustrated just want to fix hole shot with out hurting the motor

Stay with current prop and motor sitting as is, shift weight up front and don't fill completely the live well. Or go for what's theoretically been suggested and buy one prop after the another while dumping money into the deep blue trying to solve the plane issue...

Buying and testing different prop models will end being an extremely costly experimentation, unless having already a full suitcase of props to try them out...

I turned 6K rpm with a 12p 4 blade prop @ 33mph wot. I turn 5500 rpm with a 14P 3 blade prop @ 38 mph with just me in the boat. Check tach setting on the back of tach. Should be a 5 or 6. Don't recall now. Google it.

The last 2 boats I bought were set up perfectly at the factory and perform beyond my expectations.

You said "brand new". Contact Tracker and tell them how your boat performs. They should be the ones to send you a new prop, or raise the motor, or whatever. You paid for a boat that works right - make them make it right.
