Re: KL exteriot coolant line

Warming the fuel mixture helps it to atomize better than when cold. Carbs being the inefficient things that they are have been notoriously heavy on the fuel droplets. Modern fuel injection, not so much but they need a computer to regulate properly and reliably. Under certain conditions of temperatur...

Re: Crack in keel by rudder

Well as you mentioned, pictures will help us in offering ideas but until then... Yeah, the keel on a Sportsman will not easily "pop" out, a major task to say the least. Probably a simple repair depending on the cause of the crack. There is stress on the keel in this area from the rudder turning the ...

Re: Side plank seam repair

Appears to be either some plank movement going on or a drying out of the planks. Either is to be expected in a 73 year old boat, whether it's used every season or put in non-climate controlled storage. So what to do with it? Mahogany colored Famowood is a recommended filler for some screw holes, din...

Re: Driveline vibration, what’s normal?

I would suggest disconnecting the prop shaft from the transmission to isolate the engine, then run it in gear. If you have enough clearance between the drive flanges and prop log to uncouple, try that first. If the flanges aren't already marked, mark then so they can be reassembled the same as befor...

Re: Gel Coat, Marine Paint, or Varnish for '63 Constellation

Just my opinion but I think bright finish on the hull sides will be a big challenge to get it right. Every screw that has been plugged with a compound will show through and I don't think the factory used mahogany bungs to plug the holes on the big cruisers either. You also have different non-matched...

Re: KL Vacuum Guage

Unless you're fortunate enough to have a later model with the closed crankcase breather like this picture, there's no way I know of to attach a vacuum gauge to the intake manifold. Drilling and tapping cast iron or aluminum is always risky of causing stress cracks.

Just a suggestion when you go to drill the new holes for the screws; getting the hole centered in the rub rail countersink is easier and more accurate if you use a VIX bit. It goes by other names, but it has a retractable spring loaded mandrel that centers the bit in the rub rail hole and at least b...

Re: Trailered hull bottom paint

If you have a keel support board on the trailer up towards the bow, the use of teflon strips on the carpet dramatically eases the friction of sliding the hull across the bunk. There are strips available at marine supply or boat trailer places for this. I use these on the bow keel support on my 25 fo...

Depending on the size of the screw head and how much space you have to work with, a tack puller can be useful.

All other offerings for 1955 would have been 6 cylinders like the K series. Are you getting this data...

Looking at the flywheel, for a standard rotation engine it will spin counter clockwise. In the center of the flywheel should be a 1 directional boss that a crank originally would fit into. You could try putting a wrench on one of the flywheel bolts, but if the engine is stiff, you'll be turning it c...
