    Dealer reccomends 17 or 19" prop. Which one for best MPG???

    I have a 19.5' fiberglass boat (probably around 2300lb with motor gear and passengers) with a 19" pitch prop on a Yamaha F90. The manufacturer says I can use a 17" or 19" prop on this combo but he usually uses 17". Im running at 5400 rpm top speed right now and am happy with performance. Just...

    Just bought a used F90, have some questions about operation

    I just bought a used 2005 F90. Came with 703 controls. I'm just wondering if this combination has any kind of an alarm or anything to let me know if it overheats or looses oil or any other major problem that might damage the engine. Or do I need to buy the guages with the oil...

I've been thinking about repowering with a used Yamaha 4 stroke. Really wanted a 90hp but i have a chance to buy a 60hp...

    Should my engine unlock when put in forward gear?

    Just wondering if my 92 Evinrude 65 hp (not power trim) should be unlocking itself when in forward gear. It doesnt. Im just wondering in case I hit something? Will this lock mechanism slip under a big load? I dont want to leave it unlocked either because i use reverse quite a bit when fishing.

    Hi I have a 1992 65hp WMLE. I put a tach on it last year and the grey wire was dead. Did some research and found out I can use the yellow wire from the stator and that worked fine for a few weeks then intermittently would die. Thought it was the tach so i tried another but similer problems...

    Engine Stalls in rough water???

    I have a 1992 65hp evinrude that runs fairly well. I've been having some problems with it staying idling when stopped for a few minutes in rough weather. It will idle all day in the harbour no problem but seems like once the motor starts bouncing around in bigger waves it will occasionally idle...

    Should i buy it?

    Im looking for a backup engine for my 19ft boat. A friend has an older 6 hp johnson for sale. It look the same as the one in the attached pic. Looks like its late 60's or early 70's based on what I can find. It starts and runs fairly easily but always seems to either flood itself or run lean...
