It appears the only remaining component of this Simpson washer is the frame. We are testing the endurance of a new motor and pump. Our current run time is 10 hours, so far the motor is standing up, the pump, well not so good. The battery was a gamble, the engine has a alternator and rectifier but no spec’s on the battery. so far this batter is great, strong starts

Battery:
Rechargeable 12V 15AH Sealed Lead Acid (SLA) Battery – T2 Terminals – Replacement for ZB-12-15

Motor: currently 10 hrs, 3 runs, 3 full tanks of gas

Engine is doing great, using good fuel and fuel management. I paid 304.00 but it’s a wopping 450 now, might rethink my stratgy. at the time the 15hp honda was 3 times the cost, plus I lost faith in honda in the past years

Lifan LF190F-BDQC 15 HP 420cc 4-Stroke OHV Industrial Grade Gas Engine with Electric Start, 18 Amp External Charging System and Universal Mounting Pattern

Pump:
This might be the weak link so far. after 10 hours the pressure is weak, I had purchased a pressure guage for line pressure but it failed so I dont have actual pressure but it was stronger in the beginning
