Battery & Fuel System
Won't start? Bad fuel? We handle battery replacements, fuel system cleaning, and carburetor service.
Won't start? Cranks but won't fire? Runs rough and dies? Nine times out of ten, it's a battery or fuel system issue — and Bridgeport Ski Daddies fixes these problems every single day on Lake Bridgeport.
Battery problems are the #1 reason jet skis don't start. Marine batteries take a beating — vibration, heat, moisture, and extended periods of sitting all degrade them fast. We test, diagnose, and replace batteries with the correct marine-rated battery for your specific watercraft. We also check charging systems, starters, solenoids, and wiring to make sure the new battery stays healthy.
Fuel system problems are #2 — and ethanol-blended gasoline is the biggest culprit. Ethanol absorbs moisture from the air, and that moisture corrodes fuel tanks, fuel lines, injectors, and carburetors from the inside out. If your watercraft has been sitting for more than 30 days with untreated fuel, there's a good chance the fuel system needs attention.
Our fuel system services include fuel tank cleaning and flushing, fuel line inspection and replacement, fuel injector cleaning and testing, carburetor rebuild (for older models), fuel pump testing and replacement, fuel filter replacement, and ethanol damage repair. We also offer preventative fuel treatment to protect your system between rides.
Most battery and fuel system issues can be diagnosed and repaired on-site with our mobile service. Call (817) 915-3266 or request a quote — we'll get you started again.

Frequently Asked Questions
Why does ethanol ruin marine engines?
Ethanol absorbs moisture from the air (it's hygroscopic). That moisture corrodes fuel tanks, lines, and injectors from the inside. It also degrades rubber fuel lines and gaskets. It's the #1 fuel problem we see on Lake Bridgeport.
How long does a marine battery last?
Typically 2–4 years depending on usage, maintenance, and storage conditions. Using a battery maintainer during off-season storage can extend life significantly.
My jet ski cranks but won't start. What's wrong?
If it cranks (you hear the engine turning over) but won't fire, it's almost always fuel or spark. Old fuel, clogged injectors, a bad fuel pump, or fouled spark plugs are the usual suspects. We diagnose on-site.
Can you clean my fuel system without replacing everything?
Often, yes. Fuel injector cleaning, tank flushing, and fresh fuel treatment can restore a system without full replacement — if caught early. The longer bad fuel sits, the more damage it does.
