Re: New member - Water in oil in 307 V-8

For running/flushing on a trailer, I found one of those ritzy snap-on garden
hose adapters fit just about perfect into the lower (circular) fresh water
inlet on my OMC stern drive (1967 Johnson Reveler 155 Hp). I use a small
piece of "cloth" duct (or electrical) tape to snug/seal it, then another
larger piece across the forward facing inlet. Hook it up to a garden hose,
turn the water on and it works like a charm. I've been using this method
the past 5-10 years and like it much better than the garbage can/tub filled
with water route I used previously. Only caution is to remove the tape
immediately after finishing. Don't risk leaving it on until spring thinking
you'll use it again for the spring flush -- tape is a lot cheaper than what
could happen if you forget and run the engine hot (idiot lights aren't
always reliable either).

If you store your boat outside, I found the straps rotted and ripped off
just as easy as the plastic clips. After our 3rd OE top, we had a custom
made cover that added snaps arund the hull just below the rub rail and a
draw string final. I had to reinforce the corners on the windshield,
otherwise it's held up far better than any of the OE tops did with similar
levels of care.
