    Update to my bogging/stalling 3.7L

    Catch-up; When I 1st got the boat (almost 2 mos. ago), would bog and immediately stall if given throttle. Idle speed was 'ok'. Changed a bunch of stuff, which could be said as throwing parts at it, but most were regular tune-up items. Emptied fuel, and refilled with non-ethanol. Changed the...

    WOT rpm Question

    Most, if not all of us, know what the recommended rpm's at WOT is or should be on our boat, based on either the label on the motor, or the owner's manual/user's guide. Mine is 4400-4800. My question is this; 4400-4800 based on what? What prop were they using? Right now I'm running 4100 @ wot...

    Am I gonna sink my boat?

    Might be a stupid q, but... I just got a new power steering cooler unit, as mine was apparently leaking. It's a 1984 Mercruiser 488 (170), and I know it uses raw water for the cooling side on the cooler. I keep the boat in the water. If I remove the old unit, will I get water pouring in, and...

    Brass Props?

    Are brass props any good? I have a SS 19"p now, but want to try a 17"p (only getting to 4100-4200 rpms with the 19', should be between 4400-4800. It's a Marc 488 w/Alpha I Gen I outdrive. I can get a 17'p brass quicksilver for $40, and was wondering if it's worth the $$$ to see if the...

    Spitting gas when not running

    A young girl that works in the pizza joint next to my store has a scooter, and it spits gas when it's turned off. I know nothing about scooters. It dribbles, drips, and then spits gas out of a lower clear tube coming off her carb. Anyone know what is causing this, and how we can fix it? Sorry, I...

    Running Lights

    I know I can easily look this up in my Chapman, but I figure some may benefit if I asked it here. Aside from the red/greens, my boat has a transom (white) light, and an all-around light mounted on the windshield. At night, the forward all-around blinds me. Since I have a transom light, can I...

    Keeping your prop clean

    For those of you who keep your boat in the water, is there some way to keep your prop clean from growth? It seems every few days (or at least once a week), I'm in the water scrubbing green hair off my prop. It's stainless, to boot!

    Old threads and Cadets

    What's the deal lately? It seems that every third post by a cadet is on a thread that is older then dirt. Is it just me being crotchety, or does this annoy (probably a stronger word then I really want to use) others? Mods - when replying to a post that hasn't had a post in over a certain amount...

    7 'Boaters' rescued...

    These people were so crazy lucky, they should play the lottery. They had PFD's, but read the article to see what they didn't have. You'll understand why I put the word boaters in quotes. IMO, they weren't... Boaters Saved

    The saga continues...

    Ok, quick recap; 1984 Merc 488 bogs down after some time, and will most often times stall. This can be at WOT, or 1/2 throttle, or even just over idle (around 1500rpm). I've changed a bunch of stuff (including all the fuel), all fuel system filters are new, gave it a tune up, new coil, and...

    Condensate in fuel

    I put in a new f/w separator about 3 weeks ago, drained the old fuel, tested (with Kolor Kut) for water in the old fuel before removing, and am using only non-ethanol fuel. The other day, I was drained my fws, and there was water. Hmm. Today, when I opened the fuel cap, I noticed condensation on...

    Cleaning a fuel tank in boat

    It appears as though I need to completely clean my tank. It's an 80 gal aluminum, and I don't think I can (easily/realistically) get it out without it becoming a major project. I've searched and read through post relating to this, and this is what I've gleaned from those; 1) there is nothing I...

    The most ridiculous boat launch ever

    How many Canadians does it take to launch a boat? http://www.youtube.com/watch?v=3goRfcrj1WA Long but worth it.

    How do you test...

    ...a mechanical fuel pump? Or can you? It's a mechanical fuel pump on a 488r (170) Mercruiser. Suggested that the fuel pump may be seizing when warm. How can I check this?

    iboats delivery.... wow!

    Ordered a manual for my engine on Wednesday, 8/25/10, and they said delivery would be next Thursday, 9/2/10. Don't know if it was iboats or the USPS, but I got the book today, 5 days sooner than expected! Kudos to iboats!

    Starter? Solenoid? Both?

    Been having some runability issues with my 3.7L 488r, and I think I've burnt up either the solenoid, starter, or both from trying to restart after stalling so many times. I have not been able to test the solenoid as per the sticky. I know it's one or the other, and would like to just get what I...

    Beefer's engine is breaking up at WOT

    Ummmm..... Same problem here. I was/am getting ready to have the carb rebuilt, but now after seeing that you have changed the carb, not sure if that's the path I need to go down. I've changed all my filters (at fuel pump, carb, and the fuel/water separator), changed plugs, cap, rotor, points...

    Any Carb Gurus?

    I have a Rochester QuadraJet on my 488r. The number on the carb is 17081299. Is this interchangeable with the Rochester QJ with number 17081297? Can an automotive carb be used in a marine environment?

    Power Steering fluid disappears

    My power steering fluid seems to disappear. I traced the lines, checked the ps cylinder, etc, but I can't find a leak anywhere. Could it be leaking inside the cooling cylinder? If it is, can it cause problems for other systems? Would it discharge into the water from there? The reservoir is dry...

    Octane

    I can get non-ethanol gas locally, with a 93 octane. Is the high octane ok for my 1984 MerCruiser 488r?
