Check page 95 of the manual. It has a propellor table. Depending on the model you have a 10 or 11 pitch. It’s also stamped into the propeller. Since you have a light boat, a 12 or even a 13 pitch would be fine. It will make it faster as well. Don’t go for a 14 pitch as that’s for a rubber boat.
You could try to go to 13. The beeping sound from the engine and the erratic rpms after it are the result of the engine protection system kicking in. This happens because the engine rpm went over the safe limit. The correct propeller pitch will keep the engine just under the safe rpm limit.
Hi, that's is because I lift up the engine and the propeller going out from the water. That is the alarm. Because the water pump does not suck water. I have had this engine for more than 4 years. Never problem. Start the first time and go very well. Thanks
many reasons: High-speed ESG is a device to prevent over the revolution of the engine. If the load to the engine becomes light for some reason, it runs at a higher speed than the usual. In such the case, the buzzer sounds, and the ESG is activated not to ignite the spark plug, therefore, the engine speed varies and be controlled under 6300 min-1 (rpm).
hi aleksy! my bosch is making noise when i press the water gun, but it doesn't work, i mean its on, but it makes a low noise, doesn't shoot water, and then(after like 7 8 seconds) the electricity fails, it makes shortage. is it the same problem you had?
@@MrTsonkov dear friend, a friend of mine checked with tools, the voltage and current, he said it's ok. but when i power it on, it has noise, like it stuck, low humming noise, when i press the gun, it hums, then my voltage is down. so i went on the internet to search if somebody has the same problem, I found you. i wanted to dismantle it, so i can clean it, but it has so many springs and bolts inside the engine, i afraid i won't know to put it back, i wish i would find a guide to show me how to dismantle and put it back, but didn't find. aleksy you are an obviously hardworking man, with good hands and experience, i'm not like you, so i'm afraid to damage it. god bless you brother, thanks for trying to help.
