You are correct about the AQ260... but incorrect about the AQ260 TA being 30 degrees..... unless an alternate build had been done.Sorry, the 260 is a SBC 350, with a total timing advance of 30..

Mike, that is entirely up to you! You need to be happy!Rick,
I've been reading you for a long time, and would never doubt you, so please know that's not what I'm doing..And have read you tout the YLM624AV for the 260 before..
But from my 260 manual:
clockwise rotation(seen from front)
91 octane (ron)
6-8 psi fuel pressure
Rochester 4ME carb
38A alternator output
1.3hp starter motor
Bosch HR8A spark plug
.028" plug gap
1-8-4-3-6-5-7-2 firing order
8 degrees BTDC idle timing
30 degrees @4200 rpms full advance
.014"-.019" point gap
28 degrees - 34 degrees cam angle
143 degrees t-stat starts to open
160degrees t-stat fully open
I have looked at replacing that TB IV with your recommend, but am so darn happy with it…
Am i looking at this incorrectly?
Mike
IMO, any ignition part that can fail, and can be replaced on the water....., is worthy of having a spare on board.In so far as getting a spare... Spares are warranted for parts with a known or demonstrated wear mechanism leading to failure. The Thunderboat IV has no "wear parts". A better spare philosophy would be a cap and rotor ( both sealed in a plastic bag!).
Mike, you would be very pleased with the Duo Prop lower unit behind your AQ260A.I have the same power and drive as you, from the looks of it. (Just need to get the duo prop and I'd be very happy..)
