Should run like a Raped Ape. Had a 130 on a 17.5 Malibu and would haul butt 4 guys and gear would do 40mph. Those Etec's are nice motors, I would go for it. The one thing I would watch for is where your cables go though the transom. With the extra weight on the back(that Etec is 418lbs my 130HP was 358lbs) when a couple guys and gear some times water would go into the hole that the cables are routed though. I covered the old hole over and cut a new hole higher up. Other then that you should be fine.

150 is no problem. My bud just a bought a 18 tyee lund fiberglass with a 175 verado it's supercharged I got it to 55 mph on shuwap. I also rigged it with riggers so he can fish in close at hardy and it's not too much weight and a massive motor. The boat runs sweet with it. The more the horse power the better when it comes to fishing boats but like always don't go over. Most manufactures under power all boast to cut costs down.

I have a 150 merc on my 18' Hourston, the boat just rips. In my opinion i have found the 150 a little overkill especially when i am just going 3-10 minuets away on the ECVI fishing. My boats cruising speed is about 23.1MPH 4100RPMS any slower it will not plane any faster it will just guzzle the fuel like crazy. I think if i were to ever re power i would go with a 115 or a 135.
On the other hand if i was fishing West Coast Vancouver Island i would have the 150 in a heart beat. Especially if you get into some bad weather over there you want something that will pick up and go.
The choice will really depend on what you are doing and where you are going.

every boat has a Transport Canada capacity plate on the transom. The max horsepower is not a figure somebody grabbed out of the air. It is the tested weight and strength of the transom.If you get swamped offshore without power it is the difference between floating and not floating.

Got a 115 Johnson on the back of my 16.5 D.E. and even though that's the max HP rating, it's more than enough. Does
42 mph at WOT. Next motor will be a 90 hp. Yammerjammer 2 stroke. Usually fish by myself,or one other person once
in a while,so I really don't need the extra power. I guess it depends on how big a group you will be taking out on a
regular basis to justify that much power on a boat that size.

This is incorrect. Transport Canada max power rating is derived from a formula based on hull geometry. Boats with similar length, beam and deadrise will receive the same max power rating regardless of how their manufacturers construct the transom. Formula here if you are interested, you need to scroll down a fair bit.

Same as using regular automotive parts ie. starters, alternators, removing flame arrestors can and will void coverage in the case of an accident investigation so why risk?

I have a 17 hourston with a 115 yamaha 2 stroke and it goes 40mph. Way more then you need and the max for that boat is a 115hp!!! Your bow would be up in the air with a 150 on the back. I put a bow tank in the front of mine to level out the weight. Works great!!! I get on plane at 3000 rpm and cruise up to 4100 which is 25-27 mph trimmed up.

I would say it's more about the weight difference between motors of your choice than horsepower. Like somebody else said it's up to you how fast you want to go. The larger horsepower motor is nice when you need it for those heavy loads and big seas. But at some point the boat does become ridicuously overpowered.

Thanks for the link sly karma , I was trying to put across that adding weight and horsepower grossly above the TC plate to any boat will compromise safety. The deadrise calculation does actually play into the transom height therefore the horsepower calculation. The "guide" that is posted cannot be fully understood without reading TC construction standards.

I agree, i have a friend with a 225 blackmax on an 18 sangster.. sure your first to the fishing hole but loaded up with fuel only about 2-3 inches of freeboard on the transom. a little bit of an uneasy feeling when waves are splashing over the transom when another boat goes by too close..
