    Evinrude 115 v4 - information please

    I just replaced the motor on my boat with an Evinrude 115 v4. It should be somewhere in the range of 1978-1982.<br /><br />I would like to know what fuel/oil ratio to use. I've also heard that some of these motors have a VRO (oil injection) system on them. Does that mean I don't add oil to...

    motor won't idle, stalls under load

    I have a Merc 850 that was overhauled last summer. It's been a headache ever since. I took it into the shop in the spring to have it tuned up (adjusted carbs, timing, replaced voltage regulator, new plugs, etc). The boat has always had problems with stalling under load. It usually runs...

    fouled spark plugs on merc 850 - difficult to start engine

    I've noticed that my motor is difficult to start after about 4 or 5 trips to the lake. When I remove my plugs, there is some carbon build-up and some oil on the plugs.<br /><br />If I clean the plugs and reinstall them, the motor starts right up.<br /><br />I had my carb professionally adjusted...

    Tachometer help - brand new tach is fried

    I recently purchased a Teleflex universal tach for my Merc 850. The original tach has not worked since I owned the boat. I installed the new tach as the instructions described. It worked fine.<br /><br />I thought I would try disconnecting the battery to make sure the motor ran fine on its...

    correct prop for merc 850

    I have a 85 hp merc outboard. My current prop is a 19 pitch aluminum. My tach reads 4400 at WOT (full load of people), 1000 at idle. I think I am overpropped. What should my tach read at WOT? Should I purchase a 17 or 15 pitch prop? According to a propeller catalog, 15 - 19 are available...

    Do hydrofoils work?

    I've seen various hydrofoil add-ons at the marine parts store. They claim to get the boat on a plane quicker and create a lift which will take some of the engine weight away, thus increasing speed.<br /><br />Has anyone used these? Do they work? Is it worth drilling holes in my motor?<br...

    Carburetor too rich on a Merc 850

    I think my carburetor is running to rich because:<br /><br />1) I had it overhauled last summer and the mechanic said he's running it rich for the break-in period.<br /><br />2) I have runny oil coming out of the prop area after I run it (it doesn't drip constantly).<br /><br />3) I have puddle...

    which oil should I use?

    I've been using Pennsoil synthethic in my rebuilt '76 Merc 850. I noticed in a previous post about a Bayliner that Chalkboy said don't use Pennsoil synthetic. Should I not use Pennsoil? What oil should I use?<br /><br />Thanks

    Adjusting Carburetor

    What effects does having the carburetor run rich on performance of the engine? I had my motor overhauled last summer. The mechanic said he adjusted the carburetor to run rich for the break-in period. Should I re-adjust it now that the motor is broken in, so it's not so rich?

    12V vs. 24V Trolling Motor

    I am purchasing a bow mount trolling motor for my 16' tri-hull boat. I am considering the following two trolling motors:<br /><br />Motorguide Energy EF54V: 24V, 54lbs, 42"<br />Motorguide Tracker Pro 40: 12V, 43lbs, 36"<br /><br />The Tracker Pro is about $100 cheaper, but the EF54V is much...
