What to do if the Yanmar 6LPA-STP2 fresh water (coolant) high temperature alarm comes on?
If the fresh water (coolant) high temperature alarm comes on, it could be because the coolant/fresh water in the coolant recovery tank is low. Check the coolant level and refill it.
What to do if my Yanmar 6LPA-STP2 starter does not turn or turns slowly?
If the starter doesn't turn or turns slowly (but the engine can be turned manually), consider the following: * Faulty clutch position: Shift to NEUTRAL and start. * Insufficient battery charge: Check the fluid level, recharge, or replace the battery. * Cable terminal contact failure: Remove corrosion from terminals and tighten battery cables.
