    Crossflow 115 BIG issue

    Time to pull the Bypass Cover on the Weak Cylinder and see if any of the Rings are Broken or Stuck . Press on the Ring with a flat Screwdriver, being careful not to slip. A good Ring will have a springy feel, while a broken one won't. A stuck ring won't budge. It also allows you to look at the...

    1994 sunbird 19 ft with 115 evinrude mixing oil

    To put your mind at ease, you can ensure the Fuel Tank has 50:1 premix in it for a couple of hours. Then check the Oil Tank to see if there is less Oil in it. If there is, you should be okay. If the Oil level hasn't dropped, then you know there is likely a Problem. The VRO has proven to be quite...

    3.7 to 4.3 swap

    The extra power/torque of the V8 more than covers the extra few pounds. On the Brighter Side, you could convince the Wife and Kids that they hinder the Boat's Performance, and should remain ashore. Girlfriends and Mistresses, need not be sent ashore. When I was buying my I/O, it was offered...

    7.4mpi just started running rough and with gas coming out exhaust

    Does it have spark on all the Cylinders? Just because the Wire is connected, doesn't mean the Plug is Firing. The Spark must be good enough to jump at least a 5/16" gap

    Advice on 5.7 mercruiser/vortec replacement

    Mechanical pumps were for many years and are fine as long as they are USCG approved. Replacing it with an Electric pump requires that the Pump doesn't receive Power unless the Engine is Running, or being Cranked to start, again USCG Regulations. Any any Ignition System Parts have to be USCG...

    70hp 1982 evinrude manual tilt very stiff

    With the Lock engaged, it should remain up or down, depending on where the Lock Lever is set. However, if you do hit something when running, the Engine may flip up very fast and without the Shock to limit the Tilt Up, might damage the boat and/or the Transom Bracket.

    5.7 omc carb leak

    Don't go adjusting the Secondary Air Valve Spring just yet, as I have never seen one that went out of Calibration by itself. There is another device that controls how fast the Air Opens, and prevents it from opening too soon. On Most Q-jets that will be the Primary Choke Pull Off. It has a Leaky...

    Wonder if I should go IO again or go OB?

    If I were buying again, I prefer to get an Outboard, unfortunately there are no more 2 strokes being Built, and while the 4 Strokes are getting better on Acceleration, they are still a bit slower then what the Old 2 Strokes can do. My current 18 1/2 ft I/O has 5.7 in it, and it can accelerate...
