Where the joy lives
Larger Yamaha jet. Shallow-water sports without a prop; sand in the pump ends days early.
- watersports
- entertaining
Watch-outs
Honest watch-outs — so more days feel like why.
- twins-fuel
Common watch-outs
- Impeller/wear-ring damage from sand and weeds
- Overheat from clogged intakes in skinny water
- Hull stress near pump tunnel from beachings
- Electrical corrosion in splash-prone open bows
- Trailer bunks scuffing soft gelcoat
- OEM service intervals missed on 'toy' perception
Safety notes
- No jet pump = no reverse bite like a prop — practice emergency stops.
- Life jackets; keep hands clear of intake; never jet near swimmers.
