28 SI, 12V, 200A Alternator with Pulley

$551.00

Bolt-on upgrade option for most 6CTA 8.3, Late QSB 5.9, QSC 8.3, QSL 9 engines.

Also Fits M11 but we do not stock the pulley for the M11, you can re-use your old pulley.

1-Wire alternator with optional sensing lead post.  When installed on a vessel with a battery diode isolator the sensing post may be used so that the alternator can “see” battery voltage. 

Typically these are plug and play on a Cummins engine with a large frame 1 wire alternator.  If you are replacing a 3 wire alternator, you will need to make some minor adjustments to the wiring connections. 

While these alternators do have an R terminal, they are not likely compatible with the Tachometer in most Cummins Applications. 

Current Output: 200 Amp

Description

Seaboard Marine stocks alternators for all of Cummins marine engine models. Cummins has supplied their engines with many styles of alternators over the years, but the most common are the Delco Remy 15SI, 19SI, 21SI, 22SI, 24SI & 28SI models.

We offer new alternators modeled after the world-class Delco Remy units with higher amperages & upgraded regulators along with our expertise and guidance to allow “Plug & Play” replacement – Our price for direct replacement or UPGRADED units cannot be touched when you want a hassle-free installation and a quality unit.

We also offer “kits” to upgrade from the very early Bosch K1, Prestolite / Motorola, and early Delco units that were used on the earliest Cummins B-Series engines. We speak the language of alternators well, and know the Cummins engines and DC power distribution on boats like no other!
