Possible starting issue

[Krzemienr]

I have Mercury Force 90 outboard (2-stoke). Takes very long to actually start. I'm wondering if I'm doing something wrong myself. I have never owned a boat prior to this one, and only had this one running for about 4 months now. I pump the primer 2-3 times and try to start. Regardless of where I have the choke, the starter only engages for a split second. I can move the starter freely so it doesn't look seized to me. The boat sat for 5 years prior to me getting it. The carbs have been cleaned. New fuel filter and spark plugs put in. I just wanted to take the "operator error" aspect out of it before I do any electrical troubleshooting. I understand the starter should stay engaged until the cylinders fire up. It was my assumption that it would crank for more than a split second. Usually takes me 10-15 minutes to actually start. Should I be priming it more? I appreciate any input.

What year is the 90 HP Force?
It sounds like the battery is weak/not fully charged, so you should get the battery tested if any good??
Also clean the battery terminals & battery-cables (keep in mind; grounds are equally as important as Pos. wires)
After the battery is confirmed good & all cable-end in good condition and are cleaned, we still have the same issue we move on to Starter
Note; post your next question in the Force-forum,as it is still a Force

If you are still tuned to this thread, you pump the bulb till it gets firm prior to starting. A firm bulb means the carburetor bowls have filled with fuel and the metering valve inside the carb has closed off fuel so that you are able to build up pressure. While running the bulb will be soft because the engine is using fuel and the metering valves are open allowing the fuel pump to replace the fuel in the carb bowls. If it is completely flat...you can mash both sides together with light pressure, there is no fuel in the line.

In the process of your battery and cable workover "Force Power" mentioned, take your battery, fully charged, to Walmart or Autozone to name a couple, and have it "load tested". This tells you if your battery is capable of putting out the 150 amperes (give or take) required to start the engine with ample terminal voltage (aka power = volts x amps) to spin your starter adequately.

Thanks for the replies, I'll move my questions over to the other forum, and Texasmark: The battery is brand new and I installed a charger/maintainer for all 3 batteries so they are fully charged at all times.
