Install a cam with a broad power-band from 500 to 5000 RPM (revolutions per minute), ideally. Engines that are built for road use have a very narrow power-band. The transmission allows the operator to keep the RPMs in the usable range and adjust speed with the gears in the transmission. Marine transmissions have only one speed forward and one speed in reverse, leaving no way to increase speed without a proportional increase in engine RPMs. The torque generated by the engine will fall off rapidly once the power-band range is exceeded. Replacing the cam with a broad power-band type will allow the engine to deliver power as soon as the throttle opens and continue all the way through the maximum RPM.

Install a flame arrestor on the carburetor. Gas fumes are heavier than air and can fill an engine compartment. Any ignition source can cause it to detonate. The flame arrestor will prevent any flame caused by backfiring from igniting the collected gas fumes.

Use an ignition-free alternator. All alternators create sparks inside as they operate. Ignition-free alternators have screens that dissipate the heat and prevent the outside of the alternator from reaching ignition temperatures. Ensure that any other switches, pumps or devices in the engine compartment are ignition-free.

Chevrolet engines can be converted for marine use with a few simple modifications. Gasoline engines can provide strong, reliable power for boat propulsion. Parts are easy to get from auto parts dealers and can be much lower in price than marine-specific parts from a marine supply business.

Chevrolet Performance offers parts that are intended exclusively for use in competition vehicles that will only be driven on a track or off-road course. By “competition vehicles,” GM means vehicles (i) used exclusively for competitions organized and sanctioned by a local or private body and (ii) not designed for use on public streets or highways. Consumers are strongly advised not to install parts accompanied by this warning on vehicles that will be driven on public roads, as they are not designed for that purpose. The product descriptions for such parts are accompanied by the “Checkered Flag” warning icon.

Mobile: Drag finger to rotate, Drag two fingers to pan and pinch to zoom in and out.) Note: 3D Models are large files and make take a while to load especially on slow connections. 3D Model display requires a modern smartphone or desktop computer. Older devices may have poor performance. [links]

These beautiful cast stainless steel thermostat housings are designed to replace that ugly black factory cast iron unit that is original equipment on most Mercruiser applications. It’s gleaming polished finish adds sparkle to any engine. Designed to work in conjunction with the factory circulating pump and available in both standard height and low profile applications such as EFI engines etc.

Also remember the bores are siamesed. That is, there is no cooling water between the bores. Steam holes are required.<br /><br />This works fine on a car, dont know about a boat.<br /><br /><br />Ken

Marine cam so that torque kicks in at lower RPM, not essential but recommended. Other internal parts associated with temp flutuations & condensation associated with boat motors, especially with raw water cooling.<br /><br />Aldo more
