Best Features of Early and Late Model Engines - Cont'd

EARLY MODEL COOLING SYSTEMS

Our favorite feature of the early models is their wonderful full-flow cooling systems!  Late model "by-pass" type systems reduce the flow of water through the engine to maintain temperature. In early models, all water from the pump travels through the block and head, which provides a more even temperature distribution.  The increased velocity also tends to keep cooling passages a bit cleaner. Temperature is maintained externally by a Dole thermostat (seen just above the engine in the rear) which re-circulates some of the warm water back to the intake of the pump.  Of course, to us FRESH WATER COOLING IS A MUST!

FUEL SYSTEM : SOMETHING OLD AND SOMETHING NEW ! 

In this profile, we show the early model carburetor (we like the cast iron construction) with an electric (Carter type) fuel pump .  The crankcase ventilation kit is from Indigo Electronics.

The one micron in-line polishing filter gets our vote for the single most important safety feature that you can add to your engine.  This filter, along with a good quality primary fuel filter (one with a water separator), can practically eliminate carburetor flooding, which is usually caused by dirt in the float valve.

OUR CHOICE OF BEST EARLY AND LATE MODEL FEATURES

The first time around, in the late 1940’s, Mr. Hinckley chose a Universal Utility 4 for this gentleman’s sailboat.  We would like to think that he would have found this engine to be a suitable substitute.
