 Opinions on motor
First off, I am new to the site. I have been visiting the site for a year or so but decided I should join in. I am wanting to know what y'all think. I have a 18hp Copperhead on a 16x50 xpress flat bottom. I am very pleased with the performance when I am running very light loads. (24 by myself) (22 with 2 people) (18 with 3 People)- these are speeds without hunting loads. My problem is when I get it loaded down with hunters, deeks, bamboo, guns, etc. it really bogs down the 18. I would like to get the biggest motor my boat will handle, my boat is rated for a 30hp so I am looking at a 27 PD. Question is, would a 27 PD out perform a 18 Copperhead?
* I know a slick bottom 17ft boat would do better - I just cant afford it right now.

 Re: Opinions on motor
Adding that much more horsepower should make a difference, especially on loads.

 Re: Opinions on motor
I run a 31 (which is the same block as a 35) on a 1648 with a 16" transom with no problems. No water ever swamped the boat on a dead stop either. Go with the 35!

 Re: Opinions on motor
I would love to go with the 36 PD. For those of you that are running the big block on the 16ft boat, are you happy with the way it performs?

 Re: Opinions on motor
I ran a 36 PD on a 1652 Alweld short transom for over a year, and it performed pretty good. It would basically run the same speeds as a true mud hull, other than with a load, which you lose a couple mph. The only time you'll have an issue with water coming over the back is on a very steep launch or if you suddenly stop when reversing at a good speed. I've never had an issue with water coming over the back from suddenly stopping in forward, it was awfully close but never swamped over.

 Re: Opinions on motor
Thing about a short transom is you climb a stump and you're taking on water in the back then you're done.

 Re: Opinions on motor
I ran a 27 pd on a 16-44 go devil for a while and didn't like it at all. Put a 36 on it and it ran really well. I would def. build the transom up and go with a big block.

 Re: Opinions on motor
You will get more performance out of a pro drive simply because it is a surface drive not a longtail. I would look into a Go-devil SD27

 Re: Opinions on motor
I run a 27 PD on a 1638 skiff. You can load them down with 3 guys and a hunt load , you just have to take your time.
