    Installing trim gauge on old engine that has no gauge.

    Ok so here's part of the problem. The wire coming out of the trim sending unit was cut when this motor was removed from whatever boat it was on previously. So all I have is the two black wires coming from the trim sending unit. They don't go up into the engine compartment, just capped and...

    Man the fuel lines on this thing are wretched. Started poking around at them and discovered a couple small leaks. The hose/bulb from the tank to the engine is OEM brand new but the hoses internally are crap. It appears that the one from pump to carbs is a molded hose for $20 but oddly I...

    When not carrying much of a load other than me and my son (approx 400lb total) we topped at 38, but with tackle, second battery, and my 9 year old daughter we top out at 35.

    Ok Gents I raised the motor up to the top hole. As you said, getting out of the hole is a bit more work and surprisingly the speed isn't any better. I have a Whale Tail that I've tried on and off over the holiday weekend and it definitely improved holeshot BEFORE raising the motor and after, the...

    Installing trim gauge on old engine that has no gauge.

    My boat unfortunately has no wires under the dash. All I have is what's in the control box. I did successfully hook up a tach using the black, purple, and gray wires. Would the trim sending wire be in the control box? I don't recall seeing any other wires in there unused.

    Installing trim gauge on old engine that has no gauge.

    My engine is apparently on it's second or third boat. I discovered yesterday that it has a trim sending unit but my boat has no gauge for it. I'd like to install a gauge but am struggling to find proper instructions. I own the original shop manual for the engine (1980 70hp Evinrude) but...

    Fuel Tank Cleaning

    You have a nice 50 gallon raised bed garden. Maybe two 25 gallon planters if you're reasonably skilled with a jigsaw. 50 gallons is a lot of gasoline to have leaking in your boat. I know new tanks aren't cheap but it's way cheaper than a bigass boat & garage fire.

    Adding extra riding seats to small fiberglass bass boat

    I recently bought a 1987 Glasstream 1550 in superb condition as a huge upgrade to our tin can jon boat. Has a 70hp Evinrude 2-smoke. Top speed (GPS) so far is 38 mph, averages about 36 with fishing gear and 2 kids additional in it. I usually only go WOT once in a while for fun, my normal speed...

    I just pulled numbers. I leveled the boat (pad) and the cav plate. Pulling measurements from the concrete, the center of the prop is 8.25" from the pad. I see a lot of banter about putting the center of the prop 3-5" from the bottom of the boat. Either way I fish a LOT of 2ft deep water, I'm...

    I'm holding the tip of the stick rule at the transom hook. Tip of the skeg/keel is nearly 15" from the pad.

    Got it. I will do that tonight. I eventually would like to put a temp gauge up for this. After I cracked the cylinder head on my Vortec 5.7 in my truck from overheating I've become a bit of a temperature freak.

    By the way I get no "beep" when I turn the key. I'll see about locating the tan wire and grounding it out tonight to see if something buzzes.

    Tell me about my 1980 70hp Evinrude E70elcsa

    Ok, understood. I don't know how to test it. I'll look it up. I've swapped impellers before on 6hp and 7.5 hp Johnsons so I assume this is similar

    I just bought a used bass boat (1987 Glasstream 1550) that has the 70hp 1980 Evinrude. Engine seems to be in great shape. Cold cranks very easy as long as you know to push the key in to activate the primer lol. Runs smoothly, idles fine. This is the first large outboard and bass boat I've ever...

    Being cautious with possible saltwater getting into gearcase.

    I just rebuilt the gearcase seal with a used gearcase cover and new gasket, rebuilt the water pump on a 7.5hp Johnson (1983). The gearcase cover is just a 3/4" thick plastic cover that seems to also have water flowing through it up into the water pump. The drive shaft drops straight through the...

    Replacing water tube part that's obsolete on 1983 Johnson 7.5hp

    Have been having issues with my water pump, so I thought, but it turned out to be a bunched-up rubber retainer that sits at the top of the copper tube where it mates up to the engine block. I will try to call Seaway soon. It's part #69 on the 1983 J8RCTA models (I can't link out to them from...

    1983 Johnson 7.5-- can't get shift rod back into lower unit.

    I had to replace the gearcase cover/seal on my motor with one from a parts motor. The previous was cracked and seemed to prevent good water flow from the water pump. I had to remove the shift rod from the gear case, and now I cannot get it to seat. I can see down inside the gearcase the small...
