Delivery was extreem quick!
Maybe the delivery price to Croatia was a little expensive (25 Euro for an EU country) but the time it took to receive the product was impressive. Overall less expensive than to buy it here in a Volvo Penta shop so very happy with your service SVB.
Vielleicht war der Versandpreis nach Kroatien ein wenig teuer (25 Euro für ein EU-Land), aber die Zeit, die für den Erhalt des Produkts benötigt wurde, war beeindruckend. Insgesamt günstiger als hier in einem Volvo Penta-Shop zu kaufen, also sehr zufrieden mit Ihrem SVB-Service.

I had the gasket fixed to the hull by a professional with the two SVB recommended products: - Sikaflex - 291i Marine Sealant / Filler - MultiPrimer Marine / 30ml Our boat will be raised for winter storage next week, curious to see if the gasket is still there!

You need to be very careful in fixing this to the hull. If it is not done properly it will fall off around the bottom of the sail-drive and cause considerable drag. Your vessel needs to lifted from the water and dry for two to three days before you start the preparation. Take off old gasket and remove all the old glue. Sand down until all old glue is removed and also all old paint that might be under the gasket. If you fail to prepare the surface well it will not stick. Once the sanding is complete then you can begin to apply the adhesive. There are many versions and your boat yard will have the knowledge of the best one to use. My boat yard used an epoxy based glue designed for under water adhesion. Don't know the name of it. Don't use the sikaflex, it does'nt seem to work very well.

Flag of English I have Jeannaeu Sun Oddesy 409 and the shape of the opening on my boat is round. Can I still use this item to apply to cover the opening? I will appreciate with you response. Thank you.

Hi, I have changed the gasket on My Hanse 311, with has a rectangular opening. Distance of the opening was shorter then the oval strengthening line around the sail drive hole. No problem cutting with knife the recess off. The important issue is that the outside perimeter covers with some excess the opening on the boat. For adhesion I used Bostik 2 component adhesive suggested by Volvo Penta and hard push - roller for better pressing of the job. Great result, so. Ģirts, Latvia 2021

You should be carefull with adhesive. The one suggested by Volvo Penta is Bostik NE486 and curing agent Bostikure D40. Follow the instructions about layering and time gap between them and pressing/rolling.

Dear customer, it depends on a lot fo factors. Best is to have a specialist check it out in the yard or marina to assess for you.
