    Which Oil??? - Mercruiser Power Trim Pump - SAE J1171 Marine

    lolol, I KNEW someone was going to say that. We inherited this boat and I noticed las year while in the water behind the boat, that this same colored, creamy white stuff was coming out of a loose down line fitting. THAT has already been taken care of. Now I just need to clean up and refill.

    Which Oil??? - Mercruiser Power Trim Pump - SAE J1171 Marine

    I should have also asked what might happen if I put a different fluid that wasn't previously in there? I'm inclined to go get some Dextron and use it.

    Which Oil??? - Mercruiser Power Trim Pump - SAE J1171 Marine

    The boat is a 1988 Glastron and here's a picture of what the actual trim unit looks like. I'm assuming the tilt came with the boat and is about the same age?

    Which Oil??? - Mercruiser Power Trim Pump - SAE J1171 Marine

    I am getting my boat ready for this year and I noticed that my tilt reservoir had water in the bottom! I drained all of the fluid and water out. It was a milky beige color. Gross!!! Anyways, I have NO IDEA what kind of oil/fluid was in there. I've spent countless hours trying to figure out...

    Navionics App on iPad?

    I have an old Samsung 10" tablet that I have used Navionics Boating app on for years. I DO NOT have cellular service nor is wi-fi turned on, but the tablet works perfectly. Somehow the internal GPS on that Samsung Tablet does the job. As I travel in my boat it keeps up and it just works! The...

    No Tach After Replacing Stator and Trigger - Tach broken or on wrong setting?

    As mentioned in an ongoing post, I recently replaced both my trigger and stator on 1984 75Hp Mercury outboard. I get spark on all four now but now my tach doesn't work. New stator is from CDI, old was original Merc. I have two questions: 1) Can I run a long wire from my rectifier up to the tach...

    Gap between gear housing and front of prop. Could it cause cavitation?

    I gave an old 16ft boat to my son-in-law and he fixed it up and got it going for about $200! The engine is a 4 cylinder, 1990 100Hp Mercury outboard that has that two pistons work at lower RPMs until you punch the throttle. (Can't remember what that feature is called?) Anyway, When he does punch...

    I did something DUMB! How dumb was it? - Wires on wrong terminals.

    I have a 1984 75Hp mercury outboard. When connecting the terminals from the long Winter's nap, I put them on the wrong sides. It popped and sparked a bit but then stopped. NOW I am having all sorts of bad stuff happening. I replaced the Rectifier, the Stator and Trigger, and I still get a...

    Fuel Economy at Cruising Speeds 17Pitch vs 21Pitch prop

    I asked this same question last year and it turned into a 5 day long question and answer session that barely led me in the right direction. (Mostly because of my lack of boating and technical knowledge, but I DID learn what WOT meant! (Believe me, I was grateful for the input, but I think I had...

    Proppy, Prop Prop Prop! SO CONFUSING!

    My 1984 -75HP Merc had a prop marked: 12 3/4 R 21 MWC (Mercury Water Carft?) well i broke that one when I hit a rock last year, and I replaced it with a prop that FIT, (?) but wasn't the right prop. It was too big and I could never achieve full RPM for my boat. So, I can either buy an original 2...

    No Spark on 1990 - 100HP Mercury Mariner

    I am diagnosing a no spark issue on 1990 100HP Merc Mariner and I feel the culprit MAY BE the kill switch. I have, what I hope to be, a quick question that is easy to answer. IF THE KILL SWITCH really is bad, would I still get spark, but the engine just won't start, or does the kill switch...

    75 HP Stinger - 1970's or early 80's

    man I just picked up an older Johnson stinger 75 HP motor. I can't see a tag, but it has the checkered flag on the cowl. When I do research on it, it seems that a LOT of people like these outboards. Was there something special about these engines???
