Too much motor?

Post by michael.magorian » 21 Sep 2016, 11:59

So I have been sitting on an old jon boat for some time now, and decided with the winter coming on, I would start getting it back in working order again. It's an 18' shallow hull and I acquired a 65 hp Mercury for it. Is that too much motor for it? I had already planned on redoing the transom and putting some pods on it. Just curious what a few of the more experienced fellers on here thought.

Hmmmmmm ... is your life insurance policy current?

I don't mean to be so sarcastic :oops: , my apologies. OK, I'm not a jon boat guy and I didn't sleep at the Holiday Inn last night, but I did check some OEM catalogs from the late 90s for 18' jon boats and 40hp is listed as the maximum rating.

But then again, a new 2016 year Lund jon boat model 1852 (75" beam, 20" transom, 475-pound hull weight) lists 65hp as max OB for remote steering and 45hp for a tiller motor.

My earlier catalogs don't differentiate between a controls or tiller motor, so I'd go by specs (beam/weight etc.) and cross-reference to something similar to yours.

FWIW I have a 60hp on an 800-pound 16-degree deadrise V-hull tin ... and she's scary nimble and fast, hitting 40mph (setup with controls motor). I'd imagine a jon would be screaming ...

#2) 25' Parker refurb from EMPTY hull ... p?f=15&t=6
#3) 16' V-tin rebuild
#4 Procraft SV14
#5) 16' Starcraft entirely NEW Transom Skins

My Tracker III is nothing more than a 1648 jon hull and it's rated for 60hp on the sticker FWIW.

Like Dale said - just how fast do you want to go ?? S A F E L Y

Here is a boat in my neighborhood that is for sale.
as you can see, it has a 90 hp motor on it.
any motor you choose will have to be your decision to carry.
Plus, checking with your local water police may be helpful.

I agree to be careful with over-powering. As far as the Sea Ark, they are built very sturdy and are heavy. richg99

What body of water do you boat on? A smallish lake, it will be too much. A river, sounds nice or a larger lake. Open water not so much as you might get pounded to hell.
