    Yamaha 5.7L Pickup Assembly problem.

    Had the engine stripped down, bored 20-thou over, new pistons etc and a new camshaft. We got most of it re-assembeld but we have a snag trying to get the pickup assembly, part No 6T08167000 to seat properly on the boss on the inlet manifold. The best we can do is about 6mm, say 1/4" from...

    Yamaha 5.7L sterndrive engine oil info

    My 1991 yamaha sterndrive is going to have an engine overhaul this year, with the guts of the motor replaced. That said, I ran it on the muffs this morning for 15 minutes to get it nice and warm then looked at the oil pressure. I'm using the Yamaha 2-digit digital tacho, and analog temp and oil...

    Rochester 4MV choke

    Running a 1991 350 Chev to a yamaha sterndrive. The choke is not operational - it's the "divorced" type with the bimetal element in a well on the inlet manifold. So I'm considering trying to make it an electric choke. Now, outboards with the "push-the-key" choke don't have any heat sensing...

    Yamaha Sterndrive to VP-280. Upgrade?

    I've got a 1991 5.7 Yamaha sterndrive in a 23' cruiser. A friend has come across a pair of 5.7 VP 280 sterndrives and I'm considering taking one off his hands, out of the goodness of my heart. I'd be doing the swap myself. Is it worthwhile? This post -...

    Mercury 70 HP Identity?

    My neighbour has a Mercury 70HP, 3-cylinder outboard. I convinced him it's time to do an impellor change so I did a serial number check using about 8 sites where these are listed, but couldn't find it. The serial number, recorded on the plate on the port side of the transom bracket, is 8022278A...

    350 Yamaha Carbie Conversion

    1991 23' Whittley Cruisemaster Sovereign (Australian cabin boat) 1991 350 Chev turning a Yamaha sterndrive, just threw a gasket kit into the carbie. The standard choke system seems a bit tired and doesn't work. Hard to start but we can eventually get her going. Is it possible to replace the...

    Two Batteries and a Bilge Blower

    Conventional wisdom is that if you have 2 or more batteries, one should be dedicated purely to the engine and the other for all other electrical loads. Now, here's the question. I'm working now on the maintenance plan for next year. The engine will be removed and rebuilt, the leg overhauled...

    90HP 2004 Merc electrical fire

    Part of my job is looking at insurance claims and I've come across one where a 3-cylinder Merc of recent vintage had an electrical fire under the bonnet that destroyed the engine harness and a few other bits and pieces but left the boat harness alone. there was no mechanical damage. Is anyone...

    Clams, more on the tacho and new problems.

    Clams, another problem.<br />We got the engine running on muffs, had forward reverse, even the tacho came good.<br />So today we took it down the local ramp, floated her off the trailer and started the engine with little or no problem after tying up to the pontoon.<br />Gave it some time to warm...

    Blue Band 6 inline tacho

    My son, under my tutelage, has resurrected an old 115hp 6 cylinder blue band Merc.<br />We got it to run then looked at the ancillary electrics.<br />1. The tacho didn't work correctly initially but then we ran a secondary earth from the tacho to the general earth used for the gauges and it...

    Help Capt Ken, another yammie leg question

    Ok, I've got the gearshift working and decided to grease all the pivot points. Then I noticed grease oozing out of a pivot point on the port side of, I think, the gimbal ring. After a quick clean and scraping out of the grease there appears to be a cover/plug/whatever missing. Any idea what I...
