    Question on Choice of GPS Map Media

    OK, so I bit on the Garmin GPSMap 76Cx (handheld) on sale at West. I've been playing with it and am impressed so far. I also bought the 12 volt power cord and the marine mount. Now I want to add marine charts and maybe a North American street map. However, my ignorance level in this area is...

    Another Ethanol Question - Adding Fresh Fuel to Older Fuel

    I've looked at the posts here and some on-line references. One thing is not clear to me. What happens if I have a small amount of old (say 90 days) fuel in my tank and fill the tank with new fuel. Will the old fuel mix with the new fuel and form a mixture with slightly different phase...

    Proper Bunk Positioning

    I want to do some fine tuning on my trailer to improve launching ease. When I redid the bunks I just put them back in the same positions as the old ones. Now, taking a closer look, I notice they (two bunks) are not even aligned with each other. The boat is flat bottomed aft and the bunks are...

    Thoughts on LVLP Spray Guns?

    I've been using my 40 year old Sears paint spray guns for many years, spraying away at 40 - 50 psi in a cloud of atomized over-spray that drifts over my makeshift "spray booth" and over the neighborhood. I've been looking at some of the more modern alternatives, but am not interested in adding...

    Mariner 30 vs. 30A - How Much Difference?

    I've been following a thread on identifying the year of a Mariner, and, in looking at the serial number reference I realize I may have been overly optomistic about the availibility of parts for my motor. I have a 1982 Mariner, 30 HP, w/serial number 30EL 689 407533. I thought I had found...

    Marine Chart Plotter/Auto GPS Combos?

    What's the current status/selection available? The posts I've found on this topic are 2-3 years old. I'm hoping the features have improved and the prices lowered somewhat by now. I'd really like to have a chart plotter for my boat, but even with my most creative thinking haven't been able to...

    Trailer Bunk/Roller Adjustment?

    I've reviewed a number of posts on this subject and want to find out if I have it right. My boat is an aluminum Bayrunner, 15 ft. 6 in. long - a "V" in the front, transitioning to a flat bottom aft. It has an aluminum keel section, 2 inches deep, running from the bow to about 18 inches short...

    Access for Torquing Head Bolts?

    I'm going to install a cylinder head temperature gauge on my OB. The sensor mounts by removing one of the upper head bolts and bolting it on. I'm thinking it might be appropriate to re-torque all of my head bolts when I do this. Problem is, the two lowest head bolts are not accessable with a...

    Where to Purchase a Cylinder Head Temperature Gauge?

    My Mariner doesn't have any port for a water temperature gauge so I'm limited to a cylinder head gauge. Does the iboats Marine Store stock these? Can't locate one on the site. Any other sources/recommendations?

    Heat to Free Seized Shift Shaft Coupler?

    1982 Mariner, 30 HP. Upper and lower shift shafts are joined with a threaded coupling that is seized (preventing me from dropping the lower unit). I'm working with penetrating substances in an effort to free it up. I'm thinking heat will be the next step, if that is un-successful. I've read...

    Mariner Lower Unit Removal Help!

    Finally at the point where I'm going to have to drop the lower unit on my 1982 30 HP Mariner to see why its not pumping water. After reading a number of posts I got the impression that it's a piece of cake. Naturally I run into a problem right out of the chute. I have the factory service...

    Mariner Cooling Water Flow Path?

    Finally got the boat w/30 HP Mariner (1982 vintage) in the water today. Ran great for awhile, then started overheating although there was a strong stream coming out the tell-tale. Limped back in by stopping to let it cool down, then restarting and making some more headway. Hopefully no...

    Anybody Made a Kicker Mount?

    Thinking ahead, if I come up with a good buy on a 4 HP or so 2-stroke for emergency ride home - how to mount it. The store bought ones for salt water use are pretty expensive. Anybody made one? Fixed or retractable? Share photos?

    What Size Crimp Connector Do I Need ...

    .... to fasten together four #16 wires? I'm used to working w/wire nuts where there is info on the number of various sizes of wires that can be attached. The crimp connectors I can find at Kragen/hardware store don't have this sort of info.

    Is Locktite Compatible With Nylock Nuts?

    I'm fastening some things with SS bolts and nylock nuts. If I put Locktite or similar compound on the threads will it compromise the locking of the nylock nuts? Will it prevent the SS bolt an nut from corroding together? Any benefits, or a waste of time or harmful?

    What Size/Grade Pivot Bolt for a Tilt Trailer?

    I have a early 1980's Dilly tilt trailer. Light weight, constructed of galvanized channel, carries a load of about 600 lbs. fully loaded (boat, motor, gas, battery, gear, etc.). Today, while re-wiring the lights, doing what I thought was the last step in getting it ready to use, I noticed the...

    Does Anyone Understand the California DMV Trailer Lighting Requirements

    ...... for boat transporting/launching trailers [U]less than[U] 80 inches in width? I was thinking that the DMV would have the these requirements all wrapped up in a handy info sheet or booklet - no such luck (at least I can't find it on their web site). The actual requirements seem to be all...

    I have a 1982 30 HP Mariner, long shaft, electric start. Serial #689 407 533. Looking at the Sierra carb kit applications shows the 18-7770 kit for: M 689 230 100 & Up ML 689 530 100 & Up E 689 250 100 & Up EL 689 550 100 & Up The serial numbers seem to be all around mine, but no...
