All New Cummins Marine B4.5 150HP

This is a new model of marine engine from Cummins. It is a 4.5 Liter 4 cylinder, electronic diesel marine engine available in Packages up to 250HP. This one is 150HP and is set up for Keel Cooling. First impressions are that it is very smooth as compared with the older mechanical 4 cylinder 4BT or 4BTA.

Hard to believe it's been 40 years since Cummins introduced the B-Series engines! Time flies when you're having fun.

[@seancripps3530]

Does Tony recommend this four-cylinder for close coupled the v-drive or only remote like the old four 3.9-4bt ? Does it shake a lot like the old 4bt?

I am working at Charoen Marine Co., Ltd. Thailand, I am researching Cummins Q series engines.

[@PSintho]

I only have the insite program, can you recommend a tool for testing q-series engines?

[@PSintho]
