Im not going to be continuing with them.

Ive had them all- the yellows reds and blues and never got more than 2 seasons out of them. I think I one one yellow top go three once.

I still have them in my little boat, but moved to Odyssey 2150 AGM type batteries in my bigger boat.

I used to have two blue tops in mine, for awhile I thought they were both bad because they would barely turn the motor over. That's when I bought the red top for its higher cranking amps, same thing. Then I changed the battery cabling out from 2 awg to 1/0 (or maybe 2/0, I can't remember for sure) and that made a huge difference. Motor turns right over and fires right up now, great improvement.

Keep in mind there are two types of blue tops, one a dual-purpose and one a strictly deep cycle that iirc they said not to use for starting on optima's website. But it has been awhile since I looked so that may have changed.

DUDE, you got the freak of nature battery, just out of curosity, do you have amps and a bbig stereo. I am a believer that the big stereos kill batteries, thus why I replace every two years, rathe rthey need it or not. Just like impellers, I replace those every two also.

Just bought Optimas this summer...happy so far!

I think the reason to buy Optimas is because they stand up to the violence of high speed boating better than standard lead plate batteries. If you are sitting in a lab, like consumer reports, you should not see an advantage. If you slam around at high speed in an offshore boat, I think you will see a difference: they have certainly lasted much, much better for me. YMMV.

The Fountain does have a big amp, but I rarely turn on the stereo.
The Flat Bottom music comes from the 700hp engine.

two 4300 watt amps,1 1800 watt. 2 12 inch subs 4 10 inch subs and about 10 5 in speakers.. And i just use one of the batteries most of the time ....Optima Blue.

it was in my other boat for a couple years too!

I changed from an Optima blue top to a smaller Odyessy 1200.
My boat trims, and starts faster from a smaller battery. My last Odyessy in my street car lasted 8 years. I also saw a few optima failures in race boats this summer.

What kind a race boats? Mine has a magneto.

Offshore Still need a battery to start it
