First time in real APBA competition you did good. Things happen at the races and pre race prep doesn't always prevent it ;-)
In my first APBA race in new 25ssh class (with Avatar) with the new from Mercury - Merc 25ss engine, a recoil housing leg broke and no spare (now I carry one, 20/20) so I was a DNR for that whole weekend (only did 1 class as my APBA start), what a disappointment! Nobody had a spare to loan since the engine was new and others were having the same problem with the recoil housing cracking. Took some time to get used to it and fix what broke on that engine.
What sparkies are you using in the Y80?
I use NGK B10EGV (#5927) fine tip electrode with 18mm to 14mm adapters and indexed. Best plug I have found.
I agree on a dry land cold start before putting in the water, about 20 seconds with no water cooling no problem. Some Y80's do not like to start with the prop in the water and the megaphone probably somewhat under water. My Y80 starts in the water ;-)
Try a bit richer on the low speed needle also helps the mid range in the corners
Where do you have the high speed needle set?
On my Y80 set up best is at 26 clicks from bottomed, 28 clicks is 1 rev from bottom for my high speed. Each boat and prop setup requires trial and error on the high and low needle for peak revs, mid range and easy start.
What fuel octane a oil ratio are you using?
I use E-free 87 with 16:1 oil synthetic blend Pennzoil XLF, this oil has zip carbon build but I keep the revs 7000+ to keep the carbon down and plugs clean. Timing set at 0.210" +/- on both cylinders with buzz box, I also check with a strobe light. The Y80 does not keep in time due to the factory clearance in the top needle bearing and wear, I was told the engineers gave extra bearing clearance to help get oil up in a cul de sac bearing dead end? I adjust timing often.
The Merc 25ss has a unique top bearing oiler with check valve and pressure to keep the top bearings oiled, nice design!.
Happy fun safe racing

With the boat repaired and the motor loaded up and my brothers boat in the trailer we set out to Fairfield for my first APBA event. our 6 hour drive down turned into 7 with boarder delays but we made it down in time for me to test on Friday. It was apparent after testing Friday my set up was still too light. But some set up tools were leant to me and some experts helped me raise the motor and tuck it in quite a lot further which supplied a stable boat set up for Saturday.
On Saturday the decision was made by the officials to run the heats back to back because of the limited ramp space at the site.
BSH was my first class up, the boat started well and while I was early at the start and had to let of the throttle not to jump I did ok placing 4th out of 7 racers. Not bad for a rookie. Second heat I ended up in traffic and while I went into the first corner with other boats I came out in 4th where I finished the heat without much issue.
As I went out for my 3rd heat I had my throttle cable jam just after the white flag dropped, I had no choice but to point the boat off the course and pull the kill switch. I had a great view of the last heat of 20ssh from the outside of the first corner.
20SSH I should have fired the motor and warmed it up on the beach but didn't. When we got it in the water it wouldn't fire and we ended up flooding it. With the help of several other racers we drug it out of the water and got it fired eventually but with more hassle than the motor has ever given me. It felt like it just wasn't getting fire for the longest time. By heat 3 it was running and while it did cut out 2 times for a second during the run I had my best heat and had a great lap and a half getting taken to school by 82B.
When we took the boat back out of the water I went to pull the plug wires to remove the prop and found the top wire cap was loose as can be. I'm thinking its poor connection was the cause of the hard start and flooding wires and caps will be replaced for piece of mind before I test again.
All in all I would say even though I missed a couple heats I felt I had a successful event. It was good for me to get out and be social and I can't say enough about how helpful the people were at the event. The SSOA, in my opinion, greatly deservers its reputation as a welcoming club with helpful people.

Where to begin,
Firstly I'll excuse myself for not keeping this updated over the past few months. Some family changes have meant that boats and a great many other things had to be put on the back burner while some more important things were sorted out. As life continues to normalize I'll make an effort to keep this thread updated.
My plan all winter had been to attend both the Enfield and Fairfield Maine races this year, unfortunately I wasn't able to make it to Enfield but my father approached me about a month ago and told me he and my brother were going to Fairfield. Friends suggested a little fun might be good for me...
On Tuesday the 11 we pulled my boat out and went to test after a terrible test session where I couldn't get any rpm out of my motor on the previous week. Cleaning of the carb woke the motor up and we kept jacking the motor up and finding more speed until I hooked in a corner and the boat threw me into the river. With only 2 days until we were supposed to leave for Fairfield my boat was cracked up and my motor was full of salt water.
Fortunately for me Adam Carruthers had come out to help test so we loaded the boat into the trailer and brought it directly to his house for emergency repairs. Within 3 hours , that's not a typo, he has a repair panel made and epoxied in! All this while he should have been prepping for Valleyfield. I am tremendously grateful for his help.
While Adam Tackled the boat we tore into the motor flushing, flushing, and flushing again. Once flushed drained and dried out with compressed air we oiled it down then put a couple cans of fogging oil through it to helpfully displace any remnants of fogging oil. We loaded the 80 into the trailer and my father picked the boat up Wednesday evening from Adams.

Deeougee,
Those could be fighting words. If anything other driver may have been sand bagging a tad because he knew he should have had a plate in.
Either way nothing but good things to say about 26b for running clean and both him and 38ce for getting by me when I showed my rookie colours and totally botched a corner. C’est la vie, I’ll get faster. -
Definitely a 300 series engine on Kevin’s boat. The fastest of fast Y80’s run 68 and the C’s are running 71-72, not a lot of separation between the engines. Not many running those above speeds either. The Y80 will out accelerate the 102 and 300 series engines also straight up. -

A nice picture taken by someone at the start finish line, we ran like this for 3 laps.
