Blotter test patterns reveal engine condition: clean oil shows defined rings, while coolant contamination shrinks the center circle by clogging pores. Fuel dilution may not create obvious visual changes—in some cases, smell is the primary indicator—making successive comparisons essential for spotting subtle shifts in engine health. See more detailed info about these tests at the end of the article. (Photo/ Drew Frye)

DIY Engine Oil Tests

Sailors obsess over the health of their engine; it is the heart of the boat (other than the rig, sails, and through-hulls). Failure is inconvenient, expensive, and even dangerous. And sailors love their maintenance, or so it seems. Anything that promises to ease the mind for a few dollars merits investigation.

Morgan 41 Used Boat Review

The Morgan 41 sloop is arguably one of the best looking of many lovely dual-purpose sailboats that the Cruising Club of America handicap rating system engendered. One owner described his boat as a Bermuda 40 for a regular Joe, only prettier. Designer Charley Morgan traces the cruiser-racers heritage, particularly below the waterline, back to Olin Stephens famous Finisterre, and Comanche, a 40-foot centerboarder built by Wirth Munroe, son of famed sharpie designer and South Florida pioneer Commodore Ralph Munroe.

Winter Sailing Tips for Diehards

For many seasonal sailors, the winterizing routine is already well underway. But there are more than a few diehard sailors in the mid-Atlantic regions, on the West Coast, and even in New England, who plan to spend all or part of the snowy season afloat. Some, we daresay, look forward to the quiet of winter. If youre toying with the idea of keeping your boat in the water during the winter, heres a short rundown on some of the more important steps to take.
The 6-hp Tohatsu SailPro, left, weighs 60 lb. and costs about $1,900. A 3-gallon gas tank, when filled, adds about 22 lb. Add to total cost the ongoing expense of fuel, oil and maintenance. The 6- hp/3000 input-watt ePropulsion Navy 3.0, right, weighs 54 lb. and costs about $6,100 including the recommended 73-lb., 48 volt/3072 watt hour E60 battery and a 25-amp charger that can top up the battery in four hours. Electric outboards are much quieter than gas models and don’t emit exhaust, but you will have to replace the expensive battery within 10 years. Prices found online in August 2025.

Prop and Shaft Check

A vessels drive train is typically defined as the components between the engine transmission coupling and the bitter end of the propeller shaft. For traditional drive trains, this includes the propeller, shaft, cutless bearing and packing gland, although the list could also be expanded to encompass ancillary items such as the rudder, engine mounts, and engine bedworks. Heres a look at two major drive train components you should know and what to look for when inspecting each. Next month well look at the components inside the boat-stuffing box, shaft, and coupler.
