Background: I have a 1979 70hp evindrude 3 cyl 2-stroke on my 1979 16 foot lund (runabout I converted to fishing craft). &0 is the max rated HP. Question: Typically how much more does a 70 HP 4-stroke weigh than a 70 hp two stroke? If I upgrade to a four, will this be too heavy? The boat does not ride particularly high as it is.

The rating is for power not for weight. My understanding is the even the new 2 strokes weigh more than the older 2 strokes. I know that i am answering this in a round about way, but most of those older runabouts also came equiped with an inboard outboard and those thing definetely outweighed the present 4 stroke outboards.

One way to get an idea of if the thing would sit to low is have some sit at the back of the boat and see what you think. I am only guessing but I think the difference would be somewhere between 100 and 200 pounds.

Or you could post this on iboats.com, they have some real boating gurus out there.

I have a 1998 Lund Mr. Pike 1650 hull. I have a 1998 Johnson 70HP 4-stroker on it. The Johnson is actually a Suzuki with Johnson casing. Anyway, this motor weighs in at a whopping 325 pounds.
It is a bit on the heavy end yes, but it IS a SWEET running motor and ALWAYS starts on the very 1st turn of the key...cold or warmed-up!
It tops out @ 5400rpm doing 38mph using the stock prop, with just me in it.

Good Luck!

      don't know what roulette is? Hi. Roulette as I think is a very cool game. Roulette has been played since the nineteenth century and every self-respecting casino, including online casinos, be sure to have it in their assortment https://aolbroadband.in/ .Games for free, which the guys provide on this site, of course, include the most popular varieties of roulette: American, European and French. The online version of roulette is no different from the well-known one from land-based casinos: it features a green table with marked numbers and betting fields, as well as a wheel with numbered cells on which the ball rotates. On this site you can learn more and even play it

      In addition to to Feichao, you can also consider the DJI Mini SE. This is also an excellent piece. However, always try to read articles and thorough reviews before buying.

      My grandmother is a very old person, and she has had a real estate company for 20 years now, she has dedicated her whole life to it, so she does not understand much about technology and is looking to modernize her business, she is one of the few real estate companies that They don't have their own application, so I see myself in charge of finding a good software developer for real estate and that type of business. Do you know any professional or company that is dedicated to it?

      Don't forget about IP Lures just west of town about 2 miles on the south side of Co. 82.    I was out on Osakis last week for a couple hours. Picked up two walleyes, one about 13" and the other a fat 14-1/2". Also a couple northerns and a handful of perch.

      Of course, you shouldn’t even ask about this, because this is the responsibility of the executor of the order, that is, the employee who will create such an application. I think it will be stated in the contract of employment if there is one and then you don't have to ask for anything.

      Shallow. Got skunked tonight. Just got chased off by the weather. Last evening was the only time the last 4 times out I caught fish. Last even was light drizzle and calm water. Water warmed up about 3-1/2 degrees since the first time out.

      It is very important not only to identify mushrooms by their appearance but also to understand whether it is useful or not, because now there are many poisonous mushrooms, and it is extremely important that no mistakes were made in the selection of such mushrooms. That's why I here https://www.mushrooms.online/mushroom-poisoning/ read a lot of interesting information about poisonous mushrooms and was able to understand more about it. I hope that I was able to help you and was really helpful to learn.
