Hi!<br />I have a Evinrude 40 hp in good working condition. It runs smooth and nice. Some months ago I bought a heavier boat, and no the engine feel a little weak, especially when I load it up. <br />I mentioned the problem for a friend and he had heard that this engine is the same as a 50 hp. The only difference is the carbs. Is it possible to upgrade it to a 50 hp by replacing the carbs?<br /><br /> :rolleyes: <br />PM

Probaly get more bang for your buck by fiddeling with the prop / motor height setup. But the pros will know about the carb swap. <br />Mac

Re: Evinrude 40 hp -85

Hi Mac!<br />Thanks for your quick reply! Im really not so familiar with the terminology so I need to ask you some dumb questions.<br />When you say "fiddeling with the prop" do you mean to put on a new prop with a different pitch? The "motor height setup", is that the same as the trim/tilt function, or do you mean how the engine is mounted on boat?<br />PM

What's the boat rated for?<br /><br />If 50hp isn't at least 75% of that rating then don't waste your money.<br /><br />Time to find a new(er) engine.

Re: Evinrude 40 hp -85

Hi!<br />According to this web site, the boat is rated for max 75hp. My boat is a stripped version of the one on these pictures. http://www.pooleboatpark.fsnet.co.uk/DellQuay15.htm <br />Of course I can get a newer and bigger engine, but that wasnt really the question!<br />I can live with the fact that the boat is slightly underpowered in some situations, but if I could add another 10 hp with a carb swap, I would concider that as an option.<br />So... is it possible or not? ;) <br />PM

Re: Evinrude 40 hp -85

Hi again!<br />Im not a mechanic, but a guess that it takes a lot more than a carb swap to make my 40 a 60!<br />Thanks a lot!<br />PM

Re: Evinrude 40 hp -85

skipmonk<br /> make sure your engine can turn about 55oo or so with the set up you have. if it wont ts time to play with props.<br />if its over propped it cant make power.

Nope, I work everyday. I own a Johnson/Evinrude (and others) dealership that has the software to create such a list. You have to know... this isn't the first time this question has ever come up!

Hi!<br />Thanks Rodbolt for a constructive contribution in my effort to squeeze a little more power out of my outboard.<br />Rabidfish! I really dont know if the list was a serious attempt in trying to help me out, or if it was for another purpose?<br />Anyway, thank you all for a great forum and many quick and good answers!<br /> :) <br />PM

No other purpose... It is the actual list to convert the 40 to a 60.<br /><br />Keep in mind some of the items are decals, etc...

Re: Evinrude 40 hp -85

Skipmunk you might look into smart tabs if you are having trouble planing off with a reasonable load.

Re: Evinrude 40 hp -85

Skipmunk;<br /><br />First make sure that your wide open throttle rpms are within range (probably about 5500 to 6000 would be correct.) If so then the best performance enhancement you will get is from the Smart Tabs, do a search for other opinions on this site. We sell a good deal of them to Europe for a very simple reason, with gas prices at 5.00 to 6.00 per gallon they tend to put smaller engines on their boat. and the Smart Tabs make a huge difference.

Re: Evinrude 40 hp -85

I could have guessed that you ment trim tabs, but I didnt know I could get trim tabs for my 15boat. When it comes to gas prices I can confirm that we must pay 6-7 $ per gallon. Would smart tabs reduce fuel consumption too?<br /><br />PM

Originally posted by nautiJohn:<br /> Skipmunk;<br /><br />Two things make up boat performance, Hull design & the motor (HP).

If the hull is not efficient then the boat will never reach maximum performance.<br /><br />Trim tabs (like flaps on airplane wings) allow you to adjust the hull design, to suite the conditions of the moment. In doing so, the efficiency improves, the speed for any given engine RPM will improve (more speed from fewer revolutions), and logically the fuel consumption will go down. How much is dependent on the other conditions but over all we have recorded between 8% to 23% depending on boat speed and hull design. If you are cruising in the 16 mph to 22 MPH the improvement will be more. <br /><br />The Smart Tabs for your boat would be ST980-40 and if you decide in the future to change engines you can simply adjust them to suite the new HP and weight. Check with your local dealers or call our distributor - <br /> Telmo Controls (47-22-672360) at Rolf Hofmost Gt. 18, P.O. Box 2906 Toyen, N-0608 Oslo, Norway<br /><br />The overall performance of your boat will improve dramatically, we guarantee it!
