    2005 40hp EFI 4-Cyl Bigfoot sn 1B005337 - Maintenance

    We just purchased a 24' pontoon which has a 2005 40hp EFI 40-Cyl Bigfoot, sn 1B005337. I've got a fair amount of experience with 2-strokes, but this is my first 4-stroke. I don't know the hours or what maintenance the previous owner did or did not do. It starts and runs well on muffs, previous...

    1983 V-150 rpm variations, leaking bottom crankshaft seals?

    Finally got time to get back to this. The exhaust cover bolts, the cover and the divider plate all came out easy. Too easy in fact - makes me suspicious the bolts were not properly torqued. The cover has definitely been off before and the gaskets seemed to be in descent shape. Most of the bolts...

    1983 V-150 rpm variations, leaking bottom crankshaft seals?

    1983 V-150 S/N 6313170 on a 28' foot Lowe Regency pontoon. After a fair amount of work last season, motor has ran well for most of this season, but recently it has become somewhat difficult to start and I also noticed that the rpms tend to vary or float around a little bit above 2000 rpm - for...

    1983 V-150 Remote Control to Engine Wire Harness Extension

    I'm looking for an extension for the remote control to engine wire harness for a 1983 v-150, s/n 6313170 with a Quicksilver Commander side-mount remote control. The existing wire harness just barely fits and is routed in such a way that it is certain that the insulation will get worn through and...

    1983 150 V-6 Black Max Service Manual and Water Pump Rebuild Kit

    I have a new to me Mercury 150. The serial number is 6313170 which I believe means it is a 1983 Mercury Black Max 150hp V-6 2.0L ELPT (long shaft, electric start, power trim). The manual that came with it is a 90-97658 (no dash for revision number). The service manual index PDF indicates that...

    1988 Lowe Regency Suncruiser repower

    I just purchased a 1988 Lowe Regency Suncruiser, RG280. It's 30 feet with a semi-enclosed cabin and upper sundeck, has U-shaped pontoons, rated for 125 hp and I guesstimate it around 3500 pounds. It came with a 1983 Mercury 150 hp Black Max. It runs, but it was hard starting and wanted to die...

    Hi all, I have a new to me 1974 Evinrude 85 hp, 85493b.

I took it for a test drive and it start and runs nicely...

    Wounded my 1975 70 HP Evinrude during decarb. Loss of power & low compression.

    I may have mortally wounded my 1975 70 HP Evinrude during decarb and I could use your experience and advice on how to proceed. Here's the back story: 1975 70 hp, long shaft (20"), mechanical shift, model 70573E on a 24' pontoon boat, turning a 13.25x13 3-blad prop at 5000 RPM WOT. In the last...

    Swap a 1975 70 hp for a 1975 115 hp

    I have a 1975 Evinrude 70 hp (70573E, long shaft) mounted on a 24' pontoon. It reaches a top speed of 20 mph @ 5000 rpm at WOT. It's a great running engine, but I have always felt it was a little under-powered for the boat, and since I boat on the Ohio River, power tilt/trim would be nice (lots...

    Control cables for a 1975 70 hp

    I have a 1975 70 hp, long shaft, mechanical shift, model 70573E. The outer plastic sheath on my throttle cable was rubbing against my transom and has worn away, exposing the inner cable which is now rusting and sticking. I would like to replace both control cables, but I can't seem to find the...

    WOT Surges/Stumbles on a 1975 70 hp

    I have a 1975 70 hp, long shaft, mechanical shift, model 70573E. It starts easily and runs great at everything except WOT of 4900 rpm (I am slightly over-propped). At WOT I am experiencing surges/stumbles from 4900 to 3300 rpm and back again. The pattern will be something like this: 15...

    Low WOT on 1975 Evinrude 70 hp

    I recently acquired a 1975 24' Riveria Cruiser pontoon. It's powered by a 1975 Evinrude 70 hp outboard, long shaft, mechanical shift, model 70573E. After doing some work on it, it starts easily, idles smoothly and accelerates well. However, it tops out at 3200 rpm and around 12 MPH per GPS at...

    Mercruiser 228 repower with truck engine

    Hello, long-time lurker, first time poster here. Please be gentle with me. I've got a 1979 Century 3000 19' bowrider. It is currently powered with a Mercruiser 228 - a SBC 5.0L with a Quadrajet and a pre-Alpha outdrive. Interior is in good shape, outdrive is functional, deck is sound, transom...
