Hello,
Purchased an 87' Searay Weekender 230 with Merc 260 and Alpha One. Ran and started when I got it but just to be safe we rebuilt outdrive and did bellows, gimbal bearing, alignment, distributor cap and rotor, sensor inside distirbutor, fuel/water separator, and drained 30 gallons of orange gas. refilled fresh gas and dropped her in. adjusted idle to about 750. temp stays at 150 deg. oil pressure about 60psi i believe.
Trip#1- Started up and idled out of river to lake. As soon as gave it gas it seemed as if really dogging/ lacking power. Wouldnt get up on plane. Knocking/rattle above 2800-3k rpms. Did not like sound so came back in. Runs well at all RPM's at dock just not under load. Checked plugs and looked good. Dbl checked plugs on distributor all lined up. Old prop was beat so put on buddies spare.
Trip #2- Idled out and hit gas and she took right off. rattle still above 3200ish rpm's. planed and doin low 30mph around 3k rpm.assumed bad prop/ spun hub. still unsure of knock. ran below knock rpms and trolled then ran in fine. put on brand new prop.
trip#3- idled out hit gas, same as 1st trip. no balls and wouldnt plane. went out to fish at 10 mph and trolled fine. changed all plugs(all looked good), changed oil -valvoline 40sae, added qt marvel oil w/ oil, cleaned fuel line screen next to carb.
trip 4- ran maybe a touch better. still getting knock under load. got up on plane and did about 20-25 at 3k rpms but had to work trim and boat to plane.
So it runs great til under load at higher rpms, but yet ran pretty good the one time? The boat was slipped last year so i know it ran some at least. Trying to out what direction to go next. Check timing? Replace carb. Any thoughts and please let me know if more info needed.
Thanks,
Jarod
