Re: Your thoughts about how to wire stereo amps, etc.

That is a great chart for conventional flooded cell batteries, and folks who use them should memorize the numbers. AGM's are very different. That is why I posted both. Is the AGM not visible? I see it is not when I looked in another browser. It shows up in Chrome but not edge. Strange. It was the s...

Re: Your thoughts about how to wire stereo amps, etc.

Steve, This is a brand specific thing, but your chart is exactly how many of the higher end AGM's are - but.............. 10.5v is 0% remaining when measured under load. The other numbers are "at rest." If you discharge down to 10.5v then disconnect the load and let the battery sit, it will graduall...

Re: What to use of outboard quits

Marc, I respect your opinion and as you said there are many different solutions to a "get home solution". I also see that several batteries with a 24 or 36 volt system would be advantageous with your set up as weight is not a factor and would get you quite a while of running time if needed. I just ...

Re: Your thoughts about how to wire stereo amps, etc.

Added clarity sake: If you draw the battery down by only 20%, you still need ABOUT 2 hours to fully charge it - even if you have a huge charger. This is because the battery simply won't draw the available amps as it nears full charge. As a healthy battery charges and discharges. the impedance change...

Re: Fuel consumption

My old Yamaha F115 on an old, heavy boat seems to use about 5 gallons per hour at a leisurely 4300 to 4400 rpm at about 15 mph. This is where I tend to cruise if I'm headed up lake. Of course my fuel consumption outpaces my MPH as I throttle up - especially being a two tube model. I have a feeling t...

Re: Your thoughts about how to wire stereo amps, etc.

Some more info. Time to reach full charge: Using a 100 ah AGM battery as an example: If you drain it by 70 ah, you have to put back more than that because nothing is 100% efficient. The efficiency of AGM's is much higher than flooded batteries, and the number varies by manufacturer, but 4% to 10% is...

Re: Your thoughts about how to wire stereo amps, etc.

Yep, you are right! If a deep cycle AGM is fully charged it can indeed sit for several months without harm. 99% of Gel/AGM/Flooded deep cycle batteries die from sulfation (undercharging) so I tend to go for overkill. But my frame of reference is often a customer driven requirement of a 10 year batte...

Re: Your thoughts about how to wire stereo amps, etc.

I’m a simple three position (A, B and A+B) switch kind of guy. With a voltmeter, I can make the best decision on what is needed, at given moment. In my particular case, I have a dedicated AGM start battery that handles the engine, instruments and running lights. I have large batteries that serve eve...

Re: What you need on your toon

You got me thinking....... I do have two boat hooks, one fore and one at the helm. But they are both telescoping so they wouldn't let me lift my dog out of the water. He does have a good "float coat" with a strong handle. Right now someone in the water or on the tube just needs to give him a little ...

Re: What to use of outboard quits

Chuck, My younger boating days (late 60's and early 70's) were Southern Left Coast offshore islands at 25-65 miles, so I can appreciate your caution and respect for redundancy! I hadn't thought about it in years, but a lot of guys ran kickers in the harbors. That's a great idea for larger lakes that...

Re: What to use of outboard quits

With calm conditions, my 25' pontoon does right at 2 mph with a trolling motor rated at 55 lbs. of thrust. Against any headwind forget it. At full throttle, it draws almost 50 amps- so that would drain a typical small outboard start battery in about 30-40 minutes. I do have enough deep cycle battery...

Re: Bigger motor

My heavy, old two tube 25' with 115 hp pulls a single skier at about 23-24 mph on very smooth water. Plenty of hole shot available with 4-6 people aboard - IF they are seated mid-to-stern. Put 4-6 adults toward the bow and the nosecones PLOW like crazy. We spend a LOT of time tubing with a large 3-4...

Re: Advice on Crest Savannah Tritoon

My thought process: - Your dealer in Ohio was happy to take your money. - Now he needs to step up to the plate. That's his job as the guy between the factory and the consumer. - He is fully capable of buying your boat back at the price that you paid, or fixing it. - Do not let him off the hook by al...

Re: Entry Level TriToons

Thank you for the education! Outboards are new to me. I spent a lot of time off the West Coast in single/twin I/O's or old V drives. I've only had my pontoon boat for about a year. My little 115hp is a one handed operation thing at any speed, so I wasn't getting it. I do appreciate the information. ...
