    Lower unit gear oil - 2001 Evinrude 150HP FICHT

    Don't use standard Gear Oils, as the Marine Versions have more EP Additive to help the Tiny Gears(compared to Gears in an Auto/Truck Dif) in the Gearcases survive.

    No water coming out of the exhaust on muffs

    180-185 is too Hot for a Raw Water Cooled Marine Engine. You didn't stick an Automotive Thermostat in it at some point?

    Can I put a 28 hp Johnson on my 14' Aluminum Sea King?

    Where I am(Canada), there are NO Laws that make it Illegal to put more Hp on a Boat than the plate recommends. There might be some Issues regarding Insurance, but I always told them the Boat had more HP(sometimes 50hp more) on it than the Plate, and I was never refused by an underwriter.

    Can I put a 28 hp Johnson on my 14' Aluminum Sea King?

    I would keep the 4 stroke, as an Anchor. The 28 would not weigh 170 lbs, I doubt it would even weigh 130. It would about the same as the 35hp below, which was about 122 lbs. It was a 20" model We had 2 14 ft Mirrocrafts, one with a 25, the other had a 35. They were rated for 35hp though

    A spark tester is quite easy to make, with a bit of wire, a dry board, a couple of clips, and a couple of nails

    no oil after cylinder head recondition

    The Roller Lifter and Cam, really changed that... However, replacing a Brand A, Lifter, with a Brand X Lifter, may complicate it. If the Motor was out of the Boat... Myself, I would tear it all apart, and replace the Bearings, the Timing Chain and Sprockets, and the Cam and Bearings, and the...

    Going back to the Original Problem of not being able to start without Copious amounts of Fuel being sprayed into the carbs It does sound like a Fuel or Induction problem. Are you using the Choke? If I remember, the Fuel Pump is integral to the Carb, and there are 2 brands of Carbs used on the...

    When you had the Engine apart, I will assume you cleaned the Ring Groves in the Piston. How did you do that? What were the Piston to Cylinder Wall Clearances? Did you put the Rings in the Cylinder, prior to installing them on the Pistons, and measure the Piston Ring Gap?

    You're certain the Float is set correctly? Don't go drilling Holes in the Piston, if they did any good Mercury would have already done it Describe your Break-in Process? What did you use to Home the Cylinders? Please don't tell me a Ball Hone... 2 Stroke Cylinder Walls wear differently than the...

    no oil after cylinder head recondition

    While you have the Lifters out, flush the Oil System with the primer. Make sure the Passages between the Lifters are clear of that sludge too. Soak the New Lifters Vertically in Oil overnight. Even when you drain the Oil from the Pan, there can still be Sludge all over the bottom of the Engine...

    Carb rebuild question

    My Volvo service Manuals don't show that number but it is for the 2002 motors. My other book doesn't have it either I suggest contacting Holley and a Volvo Penta Dealer. There are many 2300s on various VP motors, Jetting and Power Valve selection is all over the map, so the proper specs are...

    no oil after cylinder head recondition

    Take the Lifters out and then run the Priming Tool/Pump, that will verify Oil is getting to the first Lifter on the Side, and allows you to clean out any guck between the Lifters. As for the Lifters, I would either replace them, or take them apart and clean them to get all the water out of them

    Mercury 80 won't crank with plugs installed

    Removing the Plugs, allowed the Liquid to drain, removing the cause of the Hydrolock. A very slightly bent/twisted Rod, can cause Binding/Tight spots, but still allow rotation, even complete rotation of the Crankshaft.

    Prop Question... Bayliner BR185

    Diameter doesn't have as much effect as Pitch, however Pitch and Dia are only 2 Variables when it comes to Props, though a lot of Props, but not all, do increase in Diameter as Pitch drops. Blade Area, Flat or Progressive Pitch, Cup, and Rake are other things that come into Play. That is one of...

    Prop Question... Bayliner BR185

    Did the WOT Rpm Change as the Prop got Massaged? You are propped pretty close to Optimum. Dropping 4" in Pitch will unload the Engine way too much, and increase the WOT Rpms to about 5400. Try to find a 20" Prop, that should give you a couple of Hundred more Rpm. That assumption is based on the...

    no oil after cylinder head recondition

    Oil gets up to the Rocker Arms via the Lifters and the Push Rods. You say there was water in the Oil. Did you flush/clean out all the Oil passages before New Lifters were installed? Or did you reuse the old Lifters? Same goes for all the Push Rods?
