    Power trim V150 mercury

    Have not used the boat for about 18 months. This weekend gave her a check out and the power trim is not working. When I switch either up or down all I get is a click sound from down around the pump. Do you think that over time the pump has frozen or do you think there could be something else...

    Poppit valve

    no compression 150hpp V6 Mariner

    Last time I took the boat out for a spin it overheated. Have just completed a compression test and 5 of the cylinders read >120psi and No. 2 cylinder has Zero. Looks like an expensive fix. Is there a chance of it being a head gasket or being realistic do you think No. 2 cylinder will require...

    carb cleaning

    I am about to pull my carbs down for cleaning. Do you have to rinse the carbs through with a solution such as straight petrol or is there a product that is more appropriate. And do you have to soak the carbs or just thoroughly rinse them. If you have to soak, how long for.

    lower rpm at WOT

    A few weeks ago I replaced the stator, plugs and leads in my Mariner V6 150hp 1986 vintage. I only had the opportunity to take the boat out the other day and it was low on revs (4200rpm) at WOT as compared to over 5000rpm which is what she used to pull. I have a keel protector fitted to the...

    Changed the stator the other day and while replacing the part I noticed that the wire for the choke was disconnected. I reconnected the wire and starts just great. Took the boat out on the water the other day engaged choke by pushing key in and no click. Boat ran OK, just, but would only pull...

    Water temp

    I have a 86 Mariner 150hp V6. When washing the motor out using muffs the water flow from the outlet is moderate until the thermostat opens up and then water flow increases. The question is after the motor has warmed up and the flow of water has increased how hot should the water be. The water...

    Spun hub?

    I was out in the money bucket fitted with a mid 80's 150 hp V6 Mariner the other day. Anyway on one or two occasions when I applied some throttle there was a loss of power but no drop in revs and maybe a shuddering noise from the motor. The money bucket is a 20 ft fibreglass half cab which...
