- Make sure the engine has fuel
- Make sure the kill switch works
- Let the engine idle and get up to operating temperature
I warmed up the engine by idling around the lake. I was averaging about 4mph @ idle, maybe touching 5 mph depending on wind and current.
The prop wanted to dive down deep but I didn’t have to fight it that much.
The first thing I noticed was that there was a lot of vibration. A LOT. I was hoping this was because the Tracer Plate wasn’t shimmed properly so I continued to warm up the engine.
After warming up the engine, I let the engine rev up and let the Backwater cruise. It had a different feel to it when compared to a Thai longtail. It did not take much effort to keep the prop in the water but I still noticed that strong vibration.
The max speed I reached was 15mph. I also saw that the Tracer plate was diving a little bit so I stopped, added a shim, and then started running again. Adding the one shim made the tracer plate ride where I think it is supposed to. Right at or right below the waterline. If I put any downwards pressure on the handle the prop would jump out so I feel like adding another shim would be too much. Still, I was only getting 15mph and bad vibration.
So I drove and cruised and put 3 hours on the engine. Never going above 15mph and never really dropping either. The throttle lever was difficult after a while with the heavy vibration so I normally only drove for 15 minutes and then took a break for 5 minutes.
After I put a couple of hours on it, this is what my thoughts are:
- Balance – I don’t like the engine falling forward. Is there a way to fix it?
- Vibration – Lots of vibration. What could cause this or how to troubleshoot it or rule out the kit?
- Speed – an 8×4 prop, 15mph, is this a normal speed, and do you recommend a certain prop to test and go faster?
- Throttle Lever – is there a better throttle lever I could use because the static throttle lever just isn’t my style and is difficult/uncomfortable to use.
So now I need to call/email Backwater with the issues & questions I have and see what they say about it. After I talk with them, I will put all the updates in a new video.
