Matt,
The holesaw (about 3") is used to drill holes at the ends of each
hand hold cut-out. Then use the sabre saw to cut out the waste
between each hole to form two rails attached at their bases. Curve
the ends with the sabre saw . Rout the inside and outside edges and
cut them apart at the appropriate angle for your overhead/cabin top.
When installed, they should match-up perfectly. They should be
drilled square to the tops of the rails. If you're not looking to
match pre-existing holes, they can be drilled before cutting them
apart (with a long enough bit!) so you know they'll match exactly.
Hope that helps!

Water Lift Exhaust
John Vronay2006-12-03 17:29 UTC
Hi all,
I have the typical marine auxiliary diesel engine exhaust system on my CAL
2-30. I replaced the Atomic 4 with a 2 cylinder Westerbeke some years ago
and the previous owner designed and installed a larger fuel tank which
resides under the cockpit. A good set-up has worked well for several years.
My question is whether the water discharge has to be above the waterline any
time the engine is running. Im asking this because I have never filled my
diesel fuel tank (capacity 40 gallons) more than ½ until yesterday. While
underway and under power, the exhaust discharge (at the original location)
is now submerged due to the extra weight in the stern. Anyone have any
insight on this?
I know about the siphoning problems; but when the boat is at rest or under
sail, the exhaust outlet is above the waterline.

My Cal 33-2 does exactly the same thing, stock from the factory. A
contributing factor is that at steaming speeds the stern is buried in
the stern wave. As long as there is sufficient exhaust pressure to blow
the water out, I wouldn't think there would be any problem. The first
thing that would happen, I think, is that the backpressure would kill
the engine. Also, in my installation, the "exhaust elbow" or riser,
coming out of the engine is well above the water line.
A related fact is that, when bleeding your engine, you must be careful
not to fill the exhaust with water while cranking without any exhaust
pressure to blow the water out. IIRC my manual suggests disconnecting
the raw water input to the engine while bleeding, or taking the belt off
the raw water pump.

****** ABYC says the exhaust thru hull should not be underwater during the normal operation of the boat. If the exhaust thru hull is on the counter, it should be changed to the stern. Ideally, it should be high enough to keep it out of the water, and close to centerline.
