    1973 7.5 HP Evinrude lower unit reassembly question

    My bud has a 1973 long shaft 7.5 HP Evinrude. He disassembled the lower unit a number of years ago. I was going to try and help him put it back together. He has two correct manuals; a SELOC and a Clymer. Looking through both, the exploded drawings of the lower units look identical, but...

    Can someone tell me about FICHT?

    What is the actual technology? Is it a direct-injection 2-stroke? What rae the similarities to/differences from Merc OptiMax? Any links/info appreciated. Thank you in advance.

    Please tell me about FICHT

    Is this direct-injection? I am looking to mount a V6 outboard in an automobile. As such, the physical orientation (mounting angle) of the engine, and elimination of carburetors is just one issue. A real, orientation-is-no-object FI would be a good start. If you have any recommendations...

    Seloc Mariner manual?

    The iboats store lists maintenannce manuals, but I cannot find the correct one for my friend's motor (that I am helping him with this week). It is (I believe) a 1987 model. 45HP inline four, s/n is 0B2051XX. The closest available manual is: Mercury Outboards, 40-115hp, 3-4 Cylinder , 2 Stroke...

    Tilt/trim issue--Mariner 45HP

    New problem with a used boat/motor. Imagine that. :) Friend recently acquired this project. Prior owners said it had been sitting for about five years. Hull is an 87(?) Bass Tracker, engine is a Mariner 45 HP inline four of the same vintage. When he bought it, the motor was tilted full...

    Yet another Hydro-Electric shift question

    I thank you for the wealth of knowledge available here. I did a search for "Hydro-Electric shift" and read a number of threads, copied some of the better posts into a document and am using it to troubleshoot my friend's 1972 Johnson 50HP. Backing up: --It has been sitting over a year. --He has...

    Nitro--Trolling motor or kicker?

    What do you use? And how do you mount it? I have a 1984 Nitro 17 F/S and cannot seem to see how to mount either my bow-mount Minn-Kota (no real flat surfaces) or my 7.5 Merc (stern has odd angles/no flat surface close to vertical).<br />Clues are welcome, pics even better.

    Kicker questions

    Looking at buying a kicker for my 17' Nitro F&S (max placard weight about 1700#). What size do you use? I had a 5HP on my previous 17' Crestliner and it was better than rowing, but not much. I have a couple "project" Merc 7.5's that I might get around to one of these days :) and recently...

    Merc 7.5 powerhead interchangeability?

    Hello once again. You guys have always been able to answer my questions so I'm coming back. I have two "project" Merc 7.5's; one is a 78 s/s and one is an 81 l/s. Neither runs, bought them as a package deal. The long shaft (81) is seized up big-time, power head is basically junk (broken...

    Merc V-6 Prop shaft adapter?

    I bought a Laser II stainless prop for my XR-2 V-6 150HP. Took off the old prop, slid the new one on, and...the aft portion of the hub has no detents to catch the locking tabs of the washer. Dug around in the boat and found what appears to be an adapter--catches the aft portion of the spined...

    Merc V-6 carbs--identify?

    I bought a set of carbs on eBay last fall intending to use them on my 150HP XR-2 V-6. After some discussion with some of you folks on iboats, I changed my plan. Instead I bought 6 rebuild kits and rebuilt the eBay carbs first as practice, then did the ones on my motor. Now I'm planning on...

    Merc V-6 carbs

    Hello all--<br />This summer I bought a 1985 17' Nitro with a 1984 XR2 150 HP V-6. All of my (relatively minor) issues relate to idle stalling, etc, so my plan was to rebuild the carbs this winter. On eBay I recently found a set from a "late 80's 200 HP V-6" and bought them cheap, figuring...

    Merc 7.5, 9.8, 20 HP

    Okay, I'll admit I know next to nothing. I just found a junk 20 HP Merc. Can any of the parts work on my 7.5? Coils, Powerpack, recoil starter, flywheel, all look similar but until I start taking everything apart...somebody want to save me a lot of trouble? If not all this stuff goes on...

    Merc 150 V-6 idle problems

    Just bought an 83 Nitro 17'er with an 85 XR-2 150 HP Merc. The boat sat in the owner's garage for three years without running (fuel drained and winterised). Compression is good (125-135 on all six) and on the muffs, it starts right up and idles smoothly. On the water, it starts but misfires...

    Merc prop part number charts?

    Does anyone know of a website where I can fill in the merc p/n and come out with info? Seems that they all start with 48, and most have the pitch as the last two numbers, but if I have the rest it should tell me something about splines, hub size, prop material, correct? Thank you as always, Rich

    Merc 150 V-6 trim gauge

    Just bought an 83 Nitro and the trim gauge is messed up. The needle moves in the right direction, but starts at the full up position then goes even farther off the dial. At first I thought the gauge would need to be indexed to the motor's actual position, but I don't see any way to do that...

    Nitro 17' Merc 150 prop pitch?

    Anyone else have a 17' Nitro with a V-6 150 HP Merc? What pitch prop are you running, and what is your top speed? Mine (used) came with a 20", but the guy had it set up for water skiing and even at that it's too low. I know it will exceed 5500, but I don't want to find out how much it will...
