Maiden voyage took place Friday evening!
Last week I had gone through the front carb on my starboard motor and found the fuel pump dry as a bone and not pumping fuel. I replaced the clear diaphragm and check valves and it would then pump fuel through the carb when I applied suction/pressure via mouth. These carbs also have new rubber diaphragms on the jet side of the carbs.
Got everything reinstalled and running again Friday after work. We headed to the ramp and it idled good and felt strong while throttling on the trailer.
Backed off the trailer and away we went. It seemed good through the RPM ranges and didn't seem to have any dead spots. Wasn't really watching speed as I didn't trust the speedo anyways but want to say I was at or around 50 at WOT. WOT was showing about 7200 RPM on both motors, not 100% confident in rpm gauges either. But they both were in the same range and no drastic differences at speed.
A few things I noted on the run.
First: My port motor throttle is slightly too lose. It wanted to slide back on me occasionally.
Second: Definitely a smoker! (100% expected especially with premix) My friends place we generally boat with have a half mile long no wake zone through a cove to their place. We idled back there and I made sure to shut down a motor and occasionally flip flop which one was running.
Third: Starting wasn't terrible. Especially after running. No choke needed once warm and very quickly came to life and straight to idle. Even after the long no wake zone. I know how these triples shake and like to load up when idling for long periods so that was a relief.
Fourth: Steering is very tight/difficult while underway. I believe my starboard cable is worn, and me fighting with it during the transom plate removal probably didn't help any. I am going to attempt to lubricate it and see what happens. Otherwise I will be replacing it.
Fifth: My port motor seems slightly louder in terms of exhaust noise than the starboard one. I am going to investigate more on that. I know what these motors sound like in skis. The water boxes are different in comparison on these boats vs the ski boxes so the sound is also different then what I am used to. Might just be me being overly cautious.
From here I have my replacement intermediate housing for my leaking port housing. I will try to find time to replace that this week. I also ordered a new gas gauge. Went with a Faria GP9932A "Spun Silver" Gas Gauge. The finish is similar to the rpm and speedo gauges I am eyeing for a future upgrade. I also need to get a replacement bow light. And I want to install a safety lanyard. The previous owner deleted it. Those are the more immediate things on the to do list. Along with getting a temporary radio installed.
Our boating season is just around the corner so getting everything ready for actual full time weekend use is priority. Hoping to have the fuel gauge and intermediate housing finished by this weekend that way depending on weather we can do a extended shake down to really test everything.
