Doing a 300-hour service on my buddy's boat with twin 300XL's (SN 3B215946) We don't have a manual yet but plan to get one soon. I'm looking for the torque specs for:
1) Alternator bolts for belt replacement (flywheel tool and belt stretch tool ordered)
2) Thermostat bolts
3) Spark plugs (20 ft/lbs?)
Thanks!
As a side note, these lower units are so much easier to re-install with the "chisel-point" style shift shaft that you can see engaging properly compared to my 150 with the splined shift shaft that engages up inside out of view. Great design!
