Hello, im new to the world of boating, and im looking at purchasing a 14-16ft flatbottom aluminum or fiberglass, but i was wondering what size motor is good for that size, the weight would include 2-3 guys w/gear. would a 7.5 HP motor do the trick. i want to take it out on a lake and rivers.

I want to be able to get to where im going rather quick. because i want to fish not just ride all day. you know? so i would love to get a 25 HP motor but i cant find any in my budget. :( so would a sub 10hp motor do the trick or no?

thanks in advnaced :)

Re: a newbie that needs guidance on motor size.

I grew up with my dad and me in a 14' aluminum with a 10hp. We went everywhere with it, and trolled for hours and hours.

We rented a boat with a 15 once and thought we were in heaven.

I guess it depends on how far you are going to travel across water.

There is always the Max HP rating for the boat, that may make your decision for you.

Re: a newbie that needs guidance on motor size.

We fished for years in the 10 and felt safe if you keep ahead of the weather and know your water. The 15 seemed really fast for one weekend.

I just re-read your post, of course fiberglass is much heavier and will need more power to go the same speed. so if money is the issue, I would try to get aluminum. It's cheaper to tow and cheaper to push on the water.

That's my experience.

to be honest with you, i didn't even think that fiberglass was heavier. DUH, lol. :redface::rolleyes: yeah i wanted a aluminum to begin with because if i hit something and put a hole in fiberglass its a mess.

A 14' tinny with a 9.9-15 would be ideal. 15s usually weight the same as a 9.9.

Re: a newbie that needs guidance on motor size.

My boat is a 14' aluminum V bottom (lake boat). I use a 9.6 hp outboard. It will put me ( 325 lbs) and my son (165 lbs) and all our fishing gear up on plane with ease. With a third person it does slow down quite a bit but still gets where I'm headed in good fashion. If we were confronted with river currant that would also be a factor. I'm sure my boat would push against a pretty strong currant but it may not do so very fast. If my boat was a jon boat or flat bottom boat it would be harder to push through the water because of the surface area and resistance. That is the main reason I like V bottoms. But there is most always a trade off. V bottoms usually aren't as stable as jons or flat bottoms. But at 325 lbs. I don't do a lot of standing up in the boat (there are enough whales in the sea already :D). Another thing to think about is the waters you will fish mostly. Although I do fish the larger lakes in my area, a large portion of my fishing is done on smaller conservation area lakes. Most CA lakes have 10 hp. limits for you to run you motor wide open. Anything over that you must stay at idle or no wake speed. So for me anymore than 10 hp would just be overkill plus it's good for the motor to be able to "blow the cobwebs" out of it every once in a while. Hope some of this helps and am looking forward to reading some good fishing posts from you. God Bless. Dave

Re: a newbie that needs guidance on motor size.

there's a safety factor for having a larger motor that is driven by where and when you use the boat. Our john boats are used duck hunting in the salt marsh, where you have strong currents heading out the ocean inlets, sudden storms, cold weather and guys in heavy clothing with gear. Sometimes you haev to cross open, choppy bays against the wind and/or current. A small motor working against those conditions could be fatal, as could be a slow boat ride with a wet hunter back to the house.
If it were just summer time use, or small confined waters such as a municipal lake, it wouldn't be a factor.

wow thanks for the great information! yeah ill be fishing either large lakes (guntesville lake) or rivers. and the only this im worried about is if the motor is powerful enough to push the boat up the river. and once i finalize on a boat ill be back here with all my pictures and fishing stories

as a matter of fact here's some pictures while I'm at it.
first and second fish are the same but it was a 2-4-1 deal :)

a little guy but i still had to take a picture

largest catch of the day, didn't know how big he was but he was a fun little fighter

also to note, this was in about 25-29 degree weather so it was pretty cold and i was just fishing off the bank if you cant tell

oh and these were all taken by my phone. lol pretty dang good quality if you ask me.

yeah, thats why i would want a larger hp motor, however i cant seem to find one that is in my budget. i dont live on the ocean so like i said above i would only be taking it to lakes and rivers. but i sure do appreciate your input and it gives me something to think about. :)

Re: a newbie that needs guidance on motor size.

what kind of flatbottom are you talking about? A light tinny will get two people on plane without issue with a 10hp. But with larger lakes the flat bottom will not be as stable as one would think if the waves pick up. I had a 14ft jon boat out one time in a lake with a 36" bottom (48" beam), and when the winds picked up, it was not a fun boat to be in (too light and somewhat tippy). Also, with bigger waves, it's going to be a slow trip home. If it was me, and budget wasn't a huge concern, I'd be looking to get an aluminum modified v with a 25hp on it. If a lightweight aluminum is what you are looking for, then something with a wider bottom and at least a 15 on back in the 15-16 foot range.

I want something i can handle for my first boat, being only 20 I want something that's reasonably priced also (saved $1200) but something that I wont worry about getting stuck lol. that's why I'm really going for higher hp than 10. because i can get a 14 ft flat-bottom with 7.5 hp Johnson for just under 1000 and then that would leave room for insurance, and registration. but I dont know if ill be conferable in that size with that motor ya know? but thank you for your reply and if you have any other suggestions it would really help out :)

Re: a newbie that needs guidance on motor size.

do you know what make and model boat it is and what year the motor is? You can always try the 7.5hp. If you don't like it and it's a good running motor, you can probably sell it and get a higher hp motor for nearly the same price. BTW, most aluminum flat bottom boats in the 14 foot range won't be rated for more than 15hp.

Re: a newbie that needs guidance on motor size.

The good news is that looks like a pretty light (and in nice condition) boat. A 7.5 should push it fine. The bad news is THAT particular 7.5 is crap. I think it's an Eska or something like that. Most likely air cooled, finding parts will probably be difficult, and it won't perform nearly as well as a 7.5 Johnson/Evinrude/Mercury/etc. I probably wouldn't pay much more than $600 for that rig.

maybe i can cut them a deal and get me to trade one of the motor on another boat, lol. but you think 7.5 will be good enough to get me on a lake and get fishing?

Re: a newbie that needs guidance on motor size.

I have 13' Ali boat with a 15hp on it and it is JUST enough to get the boat planing with 2 up, and not a lot of gear. The max rating for my 13' is 30. I'd love to put a 25 on it.... it's crap with the 15...
