Hi, his boat with identical boat and engine, clean hull and medium load was tested with various sets of test props and then the engine running data ran through the mercury prop selector tool and they came to a conclusion of 21" props. Now .. the only difference is the possibility of slightly...
Hi .. complete new installation so no props yet and working out what would be best. The 21's on the identical boat and setup could be the way to go. I could try those for a season and if needed, update to another set. It will not hurt to have a spare set. My worry is the loading, as I cannot...
Hi, I would also say that this is a complete new engine and drive installation as part of a renovation project and as such have no meaningful data to go on.
It would be handy to find a prop selector that works as the Mercruiser one doesn't even have my drive gear ratio as part of the drop down list.
Hi apologies will look at that. The difference in weight dimensions etc. is identical, however what I don't know but trying to find out is the drive gear ratio.
Hi
I have a Mercruiser Bravo 3 drive and I have been speaking to the owner of an almost identical boat and same engine, his boat was tested with a set of test props and then the engine running data ran through the mercury prop selector tool and they came to a conclusion of 21" props.
This gave...
Hi, thank you for your responses.
I am using an engine hoist on wide plywood sheeting on the ground, as the casters do not run well in the boatyard to position the drive in place and I have a pry bar to level the bell housing.
I will probably withdraw the sterndrive and re-check, clean the...
Hi, Apologies next question…
I have managed to install the Sterndrive up to the point where I have about a 1 inch gap but it doesn’t seem to want to go further. I have tried to raise or lower and different manoeuvres to push it further but it appears to stop at this point, my guess it’s at the...
The straps on the trim cylinder bars is a good idea, I will try that.
I have re-checked and the alignment is slightly off (engine too high) as the alignment tool is not going fully home. It looked o/k at the time but that was before I knew that it had to go to the first shoulder. So, with a...
“The drive shaft isn't making it into the coupler” .. This was my initial thought. Forgive me as this is all new to me. The alignment goes in and out easily and I have the tell-tale spine marks all the way around. But.. I will need to recheck again as I am not sure now if the spline marks go all...
Hi, I wondered if someone can help please.
This is the first time I have tried installing a Bravo 3 Sterndrive and it seems to be stuck at the point shown in the photo. I cannot seem to get it passed the threads although everything “appears” to be lined up and well greased.
This is a brand new...
Dumb question alert. – newbie to Mercruisers.
All new Bravo 3 installation and I just need to install the sterndrive.
However, before installing the sterndrive the manual states “With the gear lube monitor cap removed; to purge air from the system, push in on the dribble valve stem until the...
Just an update on this if I may.
On the engine harness there are connections for the Digital Trim and the Steering Sensor and the plugs fit all o/k. What tended to throw me was the colour of the wires on the engine harness connectors is different to the senders’ connectors. Time will see.
