Re: 15hp evinrude e-tec!!!!

I fully understand your reasoning I would have to think long and hard about a 183 lb 25 or 30 hp.Even with power trim and tilt.I don't understand their reasoning of a 146 lb 15 Except they probably can build it on the same line and just detune it.Only mechanical change probably the prop.Bet it has tremendous low end grunt.
Lumping the older boats into a limited hp rating isn't accurate.
The bare bones full size Crestliner Commodore 12 from 1957 was rated at 30. hp.the Viking 14 was 60 hp and the Buccaneer 15 and 17 were 70 hp.all are tiller or remote. They did have a smaller 12 and 14 rated at 6 and 8 hp.

What's even worse when it comes to the newer motors is those in the 40hp size, I have a Duranautic 14-40 open aluminum boat which will take up to a 40hp remote motor.
I can't imagine hanging a nearly 200lb motor on that boat, let alone a 250 lb 40 hp Etec. I've been running a 1980 35 hp Johnson on it and that's by far heavy enough at about 125 lbs. The 40hp Etec is about a hundred pounds heavier than it's earlier counterpart, which would fall in the 140lb range for an electric start 20" 40hp motor from that era.

I also thought the way you do. I couldn't imagine hanging a new 40 on my small narrow '68 FD Alumacraft 14' tiller steer utility boat. But I thought I'll never know unless I'd just do it. So I did, 7 years ago. The weight improved rough water performance and the power keeps the bow down. Boat build and hull design is key. It works excellent for my boat but it is big and heavy (59cu). My light weight 78 lb 25 hp (22cu) motor works excellent also. Motor size depends on how I use my boat.

205 lb motor. Running 2/3 throttle. Boat only weight 207 lbs. Rated for 40 hp. I've had this boat 42 years and never recommending anyone to do this.
(I like all motor brands. Mercury was the only brand with a short shaft)

78 lb motor. Running WOT.

Re: 15hp evinrude e-tec!!!!

kinda funny that your motor weights more than the boat empty.... lol

I tried just about every size Johnnyrude made through the 70's-80's era, my 1981 35hp did the best overall. I also tried a 20hp Yammy 4strk, which was impressive for it's size but as heavy as my 2 stroke 35hp Johnson. I also tried a 1971 Mercury 40hp twin, and a 1987 Mercury 25hp. The 35hp Johnson was the fastest, the Merc 40 had to much weight to overcome. The 25hp Merc did really well and was a good compromise between weight and power.

If I were to have to buy a new motor for that boat, I'd most likely go for either a smaller Yamaha 4 stroke or maybe a larger Yamaha carbureted 2 stoke. Since this is a pretty narrow hull, weight on the stern has a greater affect on performance out of the hole since the added motor weight puts the stern deeper in the water.

Keeping on the subject of motor weight... I'd think you'd do well with any of those motors, especially with remote steering. Your boat must be heavy?

Pictured is the boat of my previous post. I'll let the experts ponder on it. Relating to weight and boat design, in the prop forum, I'll have them guess my prop pitch. For max. rpm it surprised me and others.
Setup was done by my marine dealer. The lower transom wood is added only for motor mounting bolts. The boat is narrow, 55" beam and round chine. It easily handles the motor weight and power. Added passenger weight is of no issue for performance. Hole shot is meaningless even with the 25 hp motor.
