    Cranking Compression Values

    We were on the subject the other day and I quoted from a 1996 (as I recall) published Merc. Service Manual for 60 Jet through 125 HP 3 and 4 cylinder Mercs of that and later era. I stated that the manual said that one COULD (nice rubber word) expect to have problems if below 120 PSI or over 15%...

    Confession Time.....Oops

    Was out a couple of days ago. Still getting used to newly acquired used boat. I have every confidence in the condition of the equipment. Get the trailer in the water, jump in, full of glee and excitement for some fun, hit the key, she rolls up like she should but won't light off....won't even...

    Turning Point Cleaver

    Been diddling with props on my newly acquired 2002 rig. Since alum props are running less than a hundred bucks and I like TP props, and I found out that my 3 blade 17 put me into the "overrev limiter", I decided to try a 4 blade 17 since I never had a 4 blade and being a senior now, cruising...

    JimS123.....Hello

    Feeling good, got some rain overnight. Cooled things off nicely. Started the morning "coffee shop" with the guy with the outdrive that drug the ramp. Saw your reply and as I was reading responses, in scrolling down through your "corral" paused on your 25 Rude and Lapstrake...... Looked over...

    Not sure I want to post this but proves a point.

    Recently got back into boating with the purchase of a 2002 Crestliner 1750 and a 115 Merc 2 stroker. Purchased from a rather large dealer of such and the engine had gone through the shop with the mechanic being a seasoned professional. It was obvious he had been through the engine...

    Stator good bad?

    Stator puts 14.5 on a good 95% charged battery at 1500 rpms (for a number). Any reason to suspect that the signal picked up for the tach could be faulty on original Rect-Regl. and new replacement? What would be the mechanisms? Coil shorted, ok it drops a couple of poles would still get a...

    2002 Heritage single axle 18' bearing buddy service

    Just acqauired. Never saw anything like it. Not a Bearing Buddy with the zerk at the center. This is obviously a non-conventional axle bearing greasing device but how does it work and what kind of service does it require...I think I read it's unique to Heritage trailers. Thanks, Mark

    Online Parts Manual

    Stumbled across this: http://www.mercurymarine.com/en/us/parts-and-accessories/parts-catalog I pulled up that site 3 or 4 times lately and every time I got different responses as how it lets me use it. One time I can just pull it up, go to the info I want and work the parts list and diagrams...

    Marine Growth

    I for one seldom consider it when responding to performance problems; just don't usually think about it as I normally trailer and boat sits on the trailer when unused. I recall one summer visiting relatives on Lake Livingston, Tx., on the Trinity river South of DFW..............Spent 2 weeks...

    Texas Taxes on a State Imported Used Boat

    Reading the TPWD rules on sales taxes (6.25%) as it applies to used boats purchased out of state. The question here is the meaning of their terminology: :......or first used in Texas.......... Not clear on whether this means a new boat and its first registration happens to be Texas (assumed a...

    Nostalgia and a couple of big bore (40 cu in, 4500 rpm) OMC 25 hps.

    Was kicking around cable steering on another thread and got me to thinking about what things used to be like, with today's age of of gee I gotta have a 300 hp outboard. Here's what we got out of 25 hp (with cable steering) back when I was growing up. These are 14' Yellow Jacket boats (built...

    Optimax 90 S.S. prop suggestions

    I think you are doing ok. Having run several engines over the years on boats on the 16-18' range, glass and alum, flat, semi-v and pad boats, 38 is a respectable speed for that engine. In answering Sea Rider's comment, (opinion) after following his posts for a year or so, he runs in a...

    Mercruiser shifter kill switch

    Visiting this site is a never ending time consuming (something for a retired guy to do when nothing else is on the agenda) learning experience that keeps the mind active. I hear that helps to ward off Alzheimers. Also when successful, you get the comfort of knowing you helped somebody enjoy...
