GM LS Marine engine conversions have grown at a speed no one could have gauged until now. Hardin Marine has been at the forefront of the LS marine engine movement for the past number of years bringing to market a cooling system and exhaust option.

But one hurdle of the engine swap on popular Bravo/Alpha applications has left boaters to fend for themselves on solutions or makeshift homegrown engine mount remedies. So the folks at Hardin took to build a direct replacement engine block mount that allows a popular GM LS1, LS2, LS3 to be dropped right back onto the OEM Stud factory mount or the High Performance Hardin Marine stud mount #620-52380. Sea Pump #625-4117 will not work with these brackets.
