Optima starting batteries

Which Optima red top battery is replacement for starting batteries for a 450 hp M11? Thanks, John

Group 34/78 is what I have. Recommend you check before buying Optima. Lots of comments about quality problems over the past couple of years.

I purchased 3 Optima red top starting batteries from Apex Batteries on line.  Put the three in the FOT, then used the best coming out for a cranking battery in my boat.  The serial nrs coming out were 0202 etc. so I thought they were the original batteries and really lasted a long time.  Called Optima and they indicated the serial nrs were for 2010 batteries.  So I have some good batteries after charging and took the old boat battery to Walmart for a $13.00 core return.  Did not have to return the cores out of the FOT to Apex (a plus).  First time I had purchased such batteries on line.  No issues,  each packaged separately due to weight.  Good deal and big savings over Sam's price of $200 each.  DAN
