FNM engines

[prokohar]

Hello everybody,

I would like to get some opinions about a matter. I have a Bayliner 28 feet long with a volvo penta engine 110 hp.
I want to go faster so I want to replace it with an FNM HPE 250.
Is it worth it to do or should I go for another engine, suggestions are welcome.

Thank you in advance
ps. This is my first post so if something is missing please tell me

Having no experience with the mentioned engine I can offer only a few general remarks

- FNM is not often praised for their support and logistic excellence. Don't know if it's fair, but it's probably to some extent a function of being an Italian company
- The HPE 250 is almost exactly the same engine as Vetus VF5.250G As far as I know Vetus offers a decent 5 years warranty, it's a Dutch company with a decent reputation and they are now part of Yanmar.
- Hyundai Seasall S250 (or maybe even S220, lower price, lower fuel consumption, significantly lower WOT-revs) could be a price competitive alternative. I've read nice words from boat owners who have re-engined with Hyundai. Plus, it's a 3.0L V6 rather than a 2.4L Inline-5 so not so heavily loaded. More torque and.... all things else being equal..... longer life-expectancy than the smaller engines.

110hp for a 28ft Bayliner does sound a bit to the sleepy side. How come so little?

Mermaid Marine are the UK distributors for FNM diesels. I am one of the Scottish agents for Mermaid so if you want more info feel free to PM me. I would be happy to help if I can. The benefits of FNM are the weight savings and performance over more industrial diesels the trade off is that they can't be loaded in the same way so whilst they are great for fast pleasure craft you can't power a trawler with them. Parts and service would be covered in the UK by Mermaid in Poole or one of their service agents around the UK and Ireland so there should not be an issue there.
Obviously since this is a forum its not really the done thing for me to talk sales but if you want any info just PM or email me.

Hi there, welcome on the forum,

I had I similar idea many years ago, replacing a petrol engine for a diesel engine in a 25ft boat.
now looking backwards, I think it was a very bad idea,
and I learned that you will never recover the expense of such a engine upgrade (unles you can get such a engine extremely cheap, and install it by yourselve)

as said above, FNM engines are not commonly used in boats,
so might be expensive for parts, maintenance, and give a very lo resale value to the boat

in your booths, I would be looking for a exchange of the boat,

if you're addicted to that boat, and if you really want to replace the engine, I would search for a affordeable or used V6 or V8 Mercruiser,
imo the best option for that boat.

What drive do you have? Depending on what engine it was desgned for, the gear ratio inside may not suit the rpm band of the engine you have/get so an extra cost in that department shouldbe considered.

I'd expect the original installation was single V8 of ~300 hp

Change the boat..... far less cost.... far less hassle.
You will never recover the cost of the engine. Not even close.

Don't forget to factor in the costs of new instrumentation, control gear, electrical modification work, new props, engine mounts/bearers, additional lifts in and out to cure snagging issues....... and ..... and.....

+2.
Pretty sure the boat was not built with that engine, was she?

Regardless, I agree with Alpha22.
Aside from all the good reasons he already mentioned, you would still not have a fast boat, by any stretch of imagination.
Bayliner and fast are two words which can't be used in the same sentence!

Oh, and welcome to the asylum.
Re. what you might be missing.... Just some pics!

it realy depends on what you want to do with the boat & how long your going to keep the boat

250hp in a 28' bayliner (assuming it isn't a flybridge model) will give you 30kts + that's enough to call it fast in my book!

the boat as is is probably not worth a great deal as it is essentially only a river boat with 110hp so selling & buying another means adding £££'s

assuming the boat is in good nick & your happy to keep it for a good while say 5-10 years then a full engine & drive repower could give you a useable reliable boat for the next few years

selling & buying again you will be looking as an older boat where the engine could give expensive trouble at any time & you will have no warranty to fall back on or the reassurance of 'new machinery'

Id hazard a guess that the FNM will be offered with a mercruiser drive so bits will be cheap & plentifull for the drive you will need to find out from the FNM dealers what the warranty terms are & whether the software for engine diagnosis is available to independent service centres or you need to return to main dealer or call them out at great cost

you need to do your homework & quiz the dealers to find out the ongoing support required etc & obviously get accurate installation costs

I wouldn't rule the Idea out but done properly you could end up with a good boat that will serve you well

good luck with the project

Well, each to their own on that!

If you would like to consider the FNM for your re-power then by all means give us a call and we can hopefully put your mind at rest with regard to product support, acquisition cost, options, service parts etc.
You are welcome to contact me directly on j.townley@powertorque.co.uk or call our head office in Coventry (02476-635757) to speak to me or as I can see above Chris Ryan has also offered his services / advice so you can contact him also.
Either way, you'll get an honest opinion and then you can weigh up the pros and cons of all options. After that - the decision is yours.
All the best
Jon

Next time I am hauled into F&M I must look out for their engine department. :smile-new::smile-new:
