From a two stroke to a four stroke

[rasbo]

Have any of you replaced a 2 stroke on your boat with a 4 stroke,if so give me the pros and cons.. same boat though

[CP]

I have.   Went from a 2 stroke Evinrude 70hp to a 4 stroke Suzuki 70hp on a 17’ Arima.  My only regret is that I waited so long to make the switch. 

Pros:
Starts and idles better
Quieter
Better gas mileage, hence better range
No mixing oil
No stink
No smoke cloud

Cons:
A bit heaver
I have to change the oil every now and then

CP nailed it. Love the 4 strokes I have. 2000 19’ Arima. Not one issue in 20 years. Quiet, no smell, dependable and great range. They are heavier.

I went from a 2 stroke to a 2 stroke. 2014 ETEC 90hp on my '04 Arima Sea Pacer. I've had 2 of them and no issues at all. First one was the 75hp and it went with my other boat when I sold it. Bought the Pacer and put a new 90 on it. More torque, faster out of the hole, quiet, no smoke, no oil to mix, just add it and mixes itself, no oil to change, no belts to change, winterizes itself, sits all winter and come Spring time starts up in quarter revolution as long as the battery is up. Only down side is they don't recommend trolling with them. I have an 8 horse Yamaha for a kicker that I use for trolling. If I was going to go with a 4 stroke it would be a Yamaha. Down side to ETEC is they quit making them this year and handed it over to Mercury. If you're going to buy a brand new motor I'd buy in Oregon. I buy mine in Astoria, darn good ETEC mechanic there. I've never owned a big 4 stroke so not to much I can say about the performance of them. Just my  Good luck with whatever one you buy.

The Suzuki is a tad faster at top speed.  I did have to add a hydrofoil to help get on plane and counter the extra weight.  My Arima is very stern heavy; 35 gals of gas, battery, kicker and downriggers are all in the stern.

I had a 25hp johnson 2 stroke on my flat bottom 14' duck boat the thing hauled butt. it was rated for 25 with remote steering but  used it as tiller steer. The only time I liked that motor was full open.  all idle speed use was horrible and the motor used a lot of fuel.

I replaced it with a 2020 Suzuki 4 stroke.  Its great because It consumes much less fuel Id dare say half. Low speed use is great, and even tho it has an electric start hand pull is easy. The down side is it is heavy, and the jump back up to 25 hp would have added another 80lbs I can only get the boat up on a plane if it is just me the dog and a bag of decoys and the dog and decoys are in the front. Any more weight and it wont fully plane. Several of my friends have the same motor and didnt experience as big a problem because they have lighter V styled hulls.

18hp mercury (old) I couldn't get to run right, to a 20hp Suzuki

The zuke has been great, but the weight is a bit much on the back.  Think I need to brace it up a bit!

On an older kalamath 16' boat

Pretty much what CP said.

Yamaha or Zuk. Plenty of power to weight ratio. For larger motors play with Prop pitch depending on your needs.

I wouldn't buy a motor from a manufacture that went out of business. Parts will become impossible to find.

[Encore 280]

I think parts for the ETECs will be around for a long long time. Shouldn't need parts anyway.

One company stood alone putting their money and research into 2 strokes.  They went bankrupt in 2000 and now in 2020 during the highest boat sales anyone can remember, BRP retired the brand and engine.  Nobody bought the name or technology or will continue producing the engines.  That probably says a lot.

[Alchase]

Went so well I would never buy another 2-stroke.
My 15 hp Yamaha 4-stroke, could troll at 0.5 mph. Hit 26 mph with four adults in my 13 ft Smokercraft. And 5 gallons of gas would last half the fishing season.
The single best feature, I did not have to inhale 2-stroke smoke all day.

[metlhead]

I miss that 2stroke smell. Grew up in the back of my dad's wooden sled to the sound and smoke from a 65 Johnson Sea Horse jet

[jamesfromseattle]

The weight difference is not quite as big as it used to be. If you’re in the 70 hp range, Yamaha has a really light 4 stroke—at least by 4 stroke standards. Similar to the weight of a 2 stroke.

You guys are great,thanks so much.i was leaning honda,but found a 4 stroke Yamaha that was a 100lbs lighter,I need that lighter weight,otherwise I have to throw fish back..lol
