Do the new motors weigh more (i've seen the chart on their weight, but how does it compare to older models), if so why? I've notice alot of 13ft whalers have between 25hp and 30hp, is this because they perform better than the older motors or is it due to weight or just owners choice? What is the transom weight limit on the 1960's era 13ft whalers?

I ran my restored 13 footer for a while with a `58 35hp Evinrude Lark, about 120lbs. The boat ran well never had a problem with porpoising. I just installed a new Merc. 25 hp 4 stroke w/o trim tilt. Weight is 157 lbs. Unfortunately I`ve been busy being retired, and haven`t run the boat with the new set up yet, but I`ll get out in the next couple of days. It will be interesting to see the change if any in the way the boat rides, I`ll let you know, New two stroke 25s (Yamaha) still weigh about 110 lbs. but are tiller motors. rich

We were planning on installing a 30-hp Yamaha on it but the engine has become a total loss last month so now the search begins all over. I really would like to try the 30 or 40-hp Yamaha 4-stroke on this Whaler. Both are rated at the same weight: 183 lbs. Wouldn't shifting some weight up front work to help porpoising and other negative effects of the heavier engine? This boat is also going to be used to do some water skiing. Not me though ... just some 15 year old kids. Erik

I will need to repower some time and am curious if the newer two strokes are any lighter. Seems that all the brands brag about their light weights, but how do they compare to the older models? Meanwhile, the old Johnson keeps on plugging..... Troy 1985 Outrage 18

The weight for your "OLD" engine is easy to find but I almost resent that "OLD" part... I have a 1985 Evinrude 150 and it is only 23 years old..... Answer to your question. 370 lbs.

It is the same weight as the Merc 25 4stroke short shaft, becuase the two motors are identical from prop nut to flywheel nut. they are both built by Tohatsu in Japan . Only the cowl and the trim on the midsection are different. Erik, move the entire interior forward 4-6inches. it does wonders for the ride. Screw the rear thwart into the top of the seat clamp. Its more comfortable, and the battery and fuel tank will fit under the seat. rich

They are the exact same motor, I recently bought the Merc version and checked the specs. and visually checked both motors to make sure they were exactly the same, as I am a fan of Japanese outboards, but not necessarily a Merc fan. All the specs including the weight is the same, 157lbs. its possible the the weight of the Tohatsu is a motor with trim-n-tilt, as I was comparing motors with out trim-n-tilt. rich

If you look at the Tohatsu page, it states near the bottom: *Weight specification is based on the lightest version Here we have to assume that the engine is: 1. Manual start 2. Tiller handle 3. Short shaft 4. No Power Trim & Tilt 5. No Gas assist Tilt 6. No Shallow water drive Weight = 174 pounds Without the above features which are an "Option", this would probably be the lightest engine available for the 25 hp Tohatsu. I will take a look at what the 25 hp Merc specifications and make another post. Edited by Joe Kriz on 09/01/08 - 4:04 PM

Site Owner Personal Page Personal Album Photo Albums Project Albums Posts: 11447 Comments: 452 Joined: 03/18/05	rich, 25 hp Merc..... 1. Short Shaft 2. Manual Start 3. No Power Trim 4. Tiller or Remote? (don't know which is actually lighter here) 5. No Shallow water drive Dry weight = 157 pounds You would have to figure out what options you have and add that weight to the 157 pounds of the lightest version of your engine.

That's as near as I can figure out. See this link for LiquidNirvana2's Evinrude pages. http://rides.webshots.com/photo/25488...4590IhhqkS
