Clean Your Props!!!!!!

I am incredulous at the number of call I have gotten for engines with problems.....no performance....no reverse....smoking..

I needa new engine.

Rule #1...Look for the simple things first.....Clean off the barnacles!!!!

It has been a bumper year for them in the Chesterpeake

No kidding. My boat was in the water for one year and and the prop looked liked a popcorn ball when I had it hauled! I have never had a prop so foul in the 25+ yrs of sailing, and I usually am a "year round" sailor.

Had a "lunch haul" just to clean the prop as I guesed fouling on it after my boat would only do about 2kts at 2500rpm - with the engine hot.

Prop-Speed at four months

I had to rehaul a cat for additional service a couple weeks ago. We applied Prop-Speed in May. The boat sat idle for much of the time since. Ran it about 45 minutes to the yard and hauled out. There were a couple tube worms near the hub which slipped off when I put my finger on them. Those "bumps" are beads of water.

Also included is a shot of the Frigoboat reefer heat exchanger, which previously was a haven for barnacles and tube worms.

Just had our diver inspect the bottom after a year in the water (54 degrees F in summer): bottom paint and zincs still effective (changed zincs anyway), but prop unrecognizable with barnacles. Sounds like it was a very good year for barnacles east and west.

Aargghh- worse than ever this year.

The marina with a lift is approximately 20 miles south on the ICW from our dock. The prop on our CSY 33 was so encrusted it would have taken hours of diving down in the 3kn currents of the murky waters to clean the prop by hand. We ended up rafting the boat to a skiff and running the entire 4 hours that way to the marina.

It made for some very exciting moments getting off the dock.

Last night we went for a great 1 1/2 hour sunset sail. The wind died as expected but we had intended a long motioring to charge the batteries. 1900 RPM and 3 1/2 knots - grrrrr.

She's out today getting her blade scrubbed...

I just finished a boat today....good old reliable A-4...it was overheating.....

No problem with impeller......to problem with water to pump....but one Barnacle had managed to make his (her?) home right at the bronze elbow at the inlet side of the pump........simple things first y'know.

Be interested in the longer term results of this.

I had my boat bottom cleaned regularily and found out by chance that the prop is not included in the deal. Embarrassing when the boat overheats and goes nowhere. Live and learn.

It should be. You need to find a different diver.

An FYI

On full keels & skeg hung cutlass bearings, like on Rangers, one has to be sure to clean out the water inlet holes so the bearing doesn't over heat.

Had one come in on the hard here last week and the holes were full of baby muscles where the rest of the bottom was fairly clean. Only around the bare metals is were they collected.
