Twin Yanmar 315's through Bravo 1 drives

Morning,

Does anyone have any experince of the above set up?

We are looking at several boats currently, one has the above set up and the other D6 370 through DPR drives. (with a fairly significant price increase)

The only experience i have of the 315 was in a rib and the turbo lag was crazy and it took an age to get over the hump...

im assuming the D6 will be more efficient less smokie and cleaner than the 315's but that is not a massive concern on a boat of this type. As a package, any suggestions on the robustness of the 315 and Bravo 1 units...

thanks in advance

I've a preference for merc over volvo, but if i was planning to keep the boat on a berth, then I'd go the volvo route. Bravos don't seem to like living in the water. Mind you, I dunno if the dpr's fare any better than a bravo, my only experience was with a pair of 290's that I had in a Sunseeker.

Out of interest, what boat is it?

I bought a Yanmar from Barrus a few years ago, which was one of a batch that had been bought back from Sealine, so that the boats could be re-engined with Volvo's.

Thanks Tony,

I understand that Volvo have managed to make Steering rams on the DPR Drives service consumables lasting around 18 months in the water!

Was this the yammers that eate the bravo 3's? Remember there were quite a few sealines being lifted and having engines changes at Saxon Wharf some time ago. Always wondered what happend to those yanmars.

Was it just the Bravo 3 drives that got eaten by the Yanmar 315's? i know there were a good few that had problems but does anyone know if it was limited to the Bravo 3 or was Bravo 1 also a problem?

I don't think they were breaking drives, it was just a package that didn't seem to work in that application.

I bought an engine/drive package that had been in one of them, and put it in one of my 26's, it was the best Yanmar I'd ever fitted, boat was quicker than the rest by 2mph, shame it sunk!!!! (Deep Purple)

My take on it is that the Bravo 3 is a very unforgiving drive, what with 2 solid hub props and loads of grip. I know quite a few motor's have ripped mounts off, hence the engine brace, (john cunningham makes the nicest one), but I've never had a problem in any of my installations, apart from a Bravo 1 breaking some gears, but that turned out to be operator error. Twin lever controls enabling the driver to shift into gear with too many revs.

Sealine had an issue on the S41 with the torque from the Yanmars blowing up the Bravo IIIs. Much of this is probably due to the mechanically un-sympathetic owners but proving it was difficult.

Some of the drives were modified with drive showers which worked ok but once the word go around about problem, many owners pushed until they got replacement KAD300s.

The 315 is a cracking engine mated with a Bravo 1 - it's something I'd consider as a package if the outboards ever go off the Phantom.

Volvo also had issues with steering rams on the early DPH drives but these should now all have been sorted under warranty. They fitted a small rubber boot to the ram which protects the seals and stops the water ingress which knackered the internals.

Hi pugracer,
We repair quite a number of these cylinders and it is always due to a build up of a calcium like substance on the rod when the owners don't move the steering lock to lock a few times every few weeks. The seals Volvo use are extremely high quality low friction which we source directly from the seal manufacturer. The cylinder in the picture is also having a rechromed rod. As you quite rightly say Volvo have addressed the lack of care from the owners by installing a rubber boot over the outside of the cylinder rod.

Interesting. everyone i have spoken to about the volvo drives has said they last roughly 18 months in the water before then need changing and that is regardless of how they are looked after!

The Bravo drive appears to have less exposed in the the water than the Volvo's but i guess they are much the same interms of replacement requirements.

Ever get the feeling that because when asked "what boat is it" and he didn't reply that maybe, he just wanted to keep it to himself

Good plan, we'll split it. First I better sell the car and the boat, and you sell your stuff and we'll share the drive time. Bagsy April till October and you can have the maintenance months

I think I was being a bit unfair giving you the colder months so here's the new fairer plan: you control the port engine, I control the starboard and we'll fit another helm just so we're both happy. I don't suppose we'll get anywhere but damn we'll have a lot of fun trying
