2003 Mariner 5hp 2 Stroke Questions

[BrAinZ]

Hi Guys,

Bought my wife a nice little Ribeye 2.5m SIB for Christmas, and got her a 2003 5HP Mariner for Valentines Day to go with it.... I love her I do!

I've no experience of this sort of engine, so I would really appreciate help with a couple of questions....

1. The engine has a BP6HS-10 Spark Plug in it currently, but I'm not sure that's correct. Can anyone confirm please?

2. I've given it a general clean and good spray of lube. Is there anything else that you guys would recommend to make sure it's fully working ready for the season?

3. In order to flush it out after use, just how much of the leg needs to be covered in water to run it and flush it through? or in other words... how big a bucket do I need?

Any help would be appreciated! THANKS!

Hello. Very clever. Must buy mine some boating gifts next year!

1) I think it's BPR7HS-10 or BP7HS-10 (no resistance plug) but can check for sure if needed ?

2) run it every now and then, general grease up etc. Dependant on how technical you can get you can change gearbox oil, impeller etc too.

3) the water intake is just under the cav plate so you need at least that in the bucket, if you did just run it with that though it would proberly stop pumping as the turbulence created restricts the intake. Better use a dust bin size etc

Hope it works out. Enjoy!

Whoa and you're still around to tell the tale - whats your secret?

Your plug is close - a BPR7HS-10 is recommended

A general service would be a good idea - loads of videos on You Tube to give you an idea of what is involved.

There is a large horizontal plate above the propeller that must be covered to run the engine.

If that rig is Hers - what is His????

[BrAinZ]

Thanks for the advice so far guys.

It was her idea to get her own little boat. She likes "practical" presents. And I've already bought her an iron, a washing machine, and a hoover for previous Birthdays

Wonder why the previous owner of the engine put a 6 rather than the 7?

I have looked around the Net for servicing tips, but maybe it's just me that couldn't find them. I thought with these engines being so common, there would be some good sites somewhere giving you all the info... just haven't found them yet!

Someone may be able to give exact specs (not got a 5hp manual here) but it's common to have a slightly hotter plug in if the thermostat has been removed.

[BrAinZ]

Why do you think they might have removed the thermostat? ... and how could I check?

hi

for the price of a service and whats included I would just get it done. if it needs parts ask for the same part but for the tohatsu as they are identical.

what is in service and the price is all listed on our website so you will know what your local dealer will do and charge.

if you log onto the brunswick site and go on the down load centre A,you can look on registrations and see the age,(if registered) and b, you can download an owners manual

[BrAinZ]

Er.... How can I log onto the Brunswick site as a normal human being, rather than a dealer?

[uncle al]

put in www.brunswickmarineemea.co then look for the download centre very small writing at the btm first click on that then click on the same again at the top and follow the props, it looks complicated but its not, good luck

[uncle al]

sorry brunswick site should end .com NOT .co

[BrAinZ]

Ahhh.. Brilliant. Found them now. THANKS!!! Would be nice if they were listed with a better description as to which years refer to which..... But beggers can't be choosers!

Really appreciate it!
