Outboard 'bang'

Kevinbwilko · Post by **Kevinbwilko** » Mon Mar 22, 2010 10:17 pm

Has anybody experienced a problem when using fullish throttle (4HP Mariner 2 stroke, old) it bangs as though hitting something but isn't every minute or so. Outboard serviced and in v good condition. Any ideas?
Thanks

Its prob the front of the leg on the back of the well, try a bit of wood behind the transom.

Have now found out what the 'bang' is ... now 'was'!!

The gearbox was jumping under load and as the engine looks like an original at 35 plus years old it's not worth spending on it.

Just bought a Parson 4 stroke 4HP as my wife gave me permission as I promised it would be quieter and not as smelly so please do not reply to this post saying it would be easy to repair!!!!!!!!!

I use to trust only my sails. Engines may seem reliable, but anything can happen at any time. When I'm sailing in the Thames Estuary and other East Coast rivers, I use to install the engine on the tender. If there are two, the most reliable one is in the tender. Then if the boat goes aground (and a day sailing on the East Coast without grounding is a bad day), The spinnaher halyard is ready on a lifeline, so I can heel the boat quickly to take her in deep water faster than the tide can go. This includes some acrobatic figures, like entering Woodbridge marina with a draught 5 ft when there is only 4 ft above the sill, or getting out of a mooring in front of Shotley when we fell asleep after lunch and there is no more than 3 ft left...

I need an engine to negotiate moorings and to a very shallow jetty mooring and do not have / use a tender so do rely on engine.

ANYWAY ... in the bottom of the engine well appears to be two hinges and something like a fastener. Should there be a hatch type cover or what? Is it important? Can anybody explain or show pics of what it should look like ... OR like the pre owner of my boat, throw them away as they do not do anythingthing so I have nothing to worry about?!
Thanks in usual anticipation

Hi Kevin,
Yes there should be a hatch which surrounds the outboard leg. It stops a lot of the outboards wash from being diverted into the well. I'm in to my second so far. The screws tend to vibrate loose and then you notice its disappeared. I've scoured the gallery for pictures and the best one is in Tadpole's collection http://www.swift18.org/~noentry/Swift18 ... bd4d0355e4 It's not that helpful but gives an idea. Hope this helps.

I have a slightly different view to this one, Apus Melba’s outboard well hull hatch Is virtually a full hatch flap with nothing more than a three or 4 finger slot removed on it’s leading edge (as standard) made from the same material as the surrounding hull aperture. The purpose of the flap was to reduce underwater drag whilst sailing only & outboard removed. When I did do racing with her I used to leave the outboard on a tender along with other weighty unneeded stuff so the flap remained bolted closed, only opened when the outboard was relocated back in the well. The small finger size slot is for cockpit drainage & hand hold to open the flap only.

If you do not intend to race the boat (without the outboard in position), then the flap/hatch becomes unnecessary (My view anyway).

Thanks for replies. Think I will wait until the boat comes home for winter and then I will have an excuse to go out any play on here for yet another little project!!!!
