Hey gang,
Does anyone have some pointers on tracking down a leak in a Lund 16
foot pike special?  Its leaking a little more than what I think a
bilge pump would fix.  I've done some initial work and would like to

Good day,
  what do you guys (especially the solar cell experts) think of this
boat?

My apologies if this shows up more than once - I'm forced to use a web-

I have the Cap'n aboard - and am still trying to get to know enough to

My name is Elliott, and I am seeking the help of as many people as I
can get. I'm doing a school project at Boston University and we need
people to fill out a quick survey that will take about 3-4 minutes to
fill out regarding a new product for kayaks.

My old sailboat has ablative bottom paint on her.  I have sanded her and
much of the old paint is gone.
Now.. which bottom paint to put on.  My first thought;  the Interlux ACT
ablative bottom paint.

I have some LEDs that I would like to use on my boat.  They currently
operate on 3 AAA batteries or 4 1/2 volts.  
Question:  What would happen if I wire them in direct to 12 v?  My
understanding is that LEDs have a fairly wide operating voltage range.

Im trying to compare a couple of yamaha 4 strokes, both long shaft, both
electric start.  the 15 and the 9.9 seem to share a common block, but with a
different carb and prop? they have exactly the same weight (50kg), same
displacement (323cm3), same compression (9.19:1), ...

The new dual axle trailer is coming along. IR now a welder. I could
use some basic math help around figuring out where to place the boat's
center of balance on the trailer. (so I can put the bunks in place) If
it were exactly between the two axles then it would have zero % tongue

But when it comes to how to plumb a system or what materials to

I am taking out the head because it has no holding tank.  Don't have the
money, time, or inclination to install a
smelly holding tank.
After the head is removed, I still will have the two lines  .. raw water

I had a lot of marine life on my prop this past season in Long Island
Sound, and think I might have found a special purpose anti-foul
solution, but cannot find a distributor.  I have read about this
product twice, cannot find someplace to purchase. The website lists a

I finally ran my 1968 55hp to death! I picked up a 1978 85hp from a
family member. The tilt motor is a 3 wire. It ran and tilted just fine
while on the boat that I removed it from. I removed it with an engine
hoist, used the tilt once while on the hoist to position it better,

Hi, I just purchased a 24 year old fiberglass canoe for cheap. I have
repaired two holes with west systems epoxy and plan to paint with
interlux brightsides linear polyurethane.  My prob is as I started to
sand one of the holes I repaired with the orbital sander, there has

Are there tools for cutting old fasteners (5/16" dia bronze) from the
inside of hulls?  If so, please advise what I can use to cut flush to
the inside of the planking.  I am adding new frames before hauling to
through fasten with new.  My boat has a fiberglass skin and I do not

Peggy--
Are there regs (Lloyds, AYC) on type of hose to run from head to thru
hull.  I just installed 1 1/2 PVC sanitation hose (the glossy white
stuff that Waste Marine sells for almost $10 a ft)?  I then realized
